Clova Note vs Daglo vs Otter vs Notta vs Whisper: The Complete 2026 AI Meeting Notes App Comparison

As of August 2026, taking meeting minutes is no longer the newest hire’s job. Hit record, and the audio becomes text, the speakers get separated, and the action items get pulled out — that is simply the baseline now. Yet when you go looking for an honest AI meeting notes app comparison, most of what turns up is stuck on 2024 information or is quietly copying pricing figures that were superseded a year ago. This guide reflects the picture as of 2 August 2026, and it will not hide the provenance of its numbers. Otter, Naver Works Clova Note, and Whisper were verified directly on their official pricing pages and official repository; the pricing for Daglo and Notta could not be read off their official pricing pages at all, so those figures come from each company’s official blog and official changelog cross-checked against multiple secondary sources. Wherever it matters, the text below flags which numbers are first-party and which are cross-checked.

Start with the numbers and it becomes obvious where the center of gravity sits in the Korean market. Naver’s Clova Note passed 6.6 million cumulative consumer sign-ups as of March 2026, growing 24% year over year (cross-confirmed by the Hankook Ilbo and Newsis). And yet, in that same window, Newsis reported Clova Note’s February 2026 MAU at 542,278 — and down for three consecutive months. Meanwhile Daglo, from Korean AI firm Action Power, had 2 million cumulative sign-ups as of April 2026 — a third of Clova Note’s base — but its MAU of 388,000 (up 35% year over year) is roughly 71% of Clova Note’s. Registered users and actual usage are two completely different stories.

Look abroad and Otter.ai dominates. Industry tallies put it at over 35 million users and more than one billion meetings transcribed, and in April 2026 the company announced a new positioning as a “Conversational Knowledge Engine.” But there is one line that is fatal for Korean users. As of August 2026, Otter does not support Korean transcription. Its official help center lists exactly six supported languages: English, Spanish, French, German, Japanese, and Chinese (Simplified). That single line drives most of the conclusions in this article.

In this guide we dissect five options — Clova Note, Daglo, Otter, Notta, and Whisper (on-device) — along five axes: pricing, free-tier limits, supported languages, speaker diarization, and security (whether processing happens on-device). In particular, we nail down the points that most comparison articles get flat-out wrong: what exactly you have to agree to in order to unlock the free 600 minutes, why Daglo Pro actually got worse after its pricing overhaul, and the fact that Naver Works Clova Note is billed per domain, not per seat.

1. Executive Summary: All Five AI Meeting Notes Services at a Glance

For readers short on time, here are the core specs of all five services as of August 2026 in a single table. Look at the Korean support row alone and your shortlist is already cut in half.

📊 Comprehensive Comparison of 5 AI Meeting Notes Apps, August 2026

The first thing that should jump out of this table is not the pricing — it is the language row. Otter is excellent on both price and features, but it cannot transcribe a Korean meeting, so for readers whose meetings run in Korean it is off the list. Flip that around: if your meetings run in English, Otter’s Business plan (unlimited transcription, 4 hours per session) is the single strongest option in this table.

There is, however, a second axis that splits these products almost as sharply as language does: will a bot walk into the online meeting on your behalf? Otter’s official pricing page lists “Joins Zoom, MS Teams, and Google Meet” as a feature of every plan, including free Basic — only the number of simultaneous meetings differs (1 on Basic, 2 on Pro, 3 on Business). Clova Note and Daglo have no auto-join bot at all, so someone has to hit record or upload the recording afterwards. For a team whose meetings are mostly remote, that single line matters second only to Korean support. The two Korean products win on Korean and lose on remote-meeting automation — that is how to read this table honestly.

2. AI Meeting Notes App Comparison: Feature Deep Dive

🟢 1) Clova Note — the default for Korean transcription

• Still “beta,” and still free: As of August 2026, the consumer version of Clova Note (clovanote.naver.com) still carries a beta label, and there is no official consumer paid plan at all. Naver’s own help text reads: “Paid features are not currently supported, so additional usage time cannot be purchased.” In other words, once you burn through your monthly cap, you cannot pay your way out of it. This is Clova Note’s single biggest structural limitation.
• 300 minutes a month, 600 if you consent: The baseline allowance is 300 minutes per month, and ticking the “consent to collection and use of personal information (optional)” box doubles it to 600 minutes per month. What matters here is what that consent actually covers. The condition for the upgrade is agreeing to let your recordings be used to train Naver’s AI. Go in knowing that the price of an extra 300 free minutes is the audio of your own meetings.
• AI summaries capped at 15 a month, Korean notes only: Summarization is limited to 15 uses per month and only works on notes transcribed into Korean. A single recording maxes out at 180 minutes (3 hours), so a half-day workshop will not fit into one file.
• The headline of the April 2026 update is automatic speaker identification: Following the 4 March 2026 announcement, the April maintenance release added automatic speaker identification to the enterprise tier (admins toggle it on or off in the Admin console). In the same release, the “service integrations” menu was removed from settings (Naver Works Core customers now get calendar linking applied automatically), shared-note notifications were split into in-service and email notifications, and screen-capture restrictions were extended to the mobile app. That same announcement included no changes to pricing or usage limits.
• For remote meetings, you are still the one pressing record: Clova Note has no bot that joins Zoom, Teams, or Google Meet on your behalf. Naver Works core customers do get automatic calendar linking, but that ties events to notes; it does not send a bot into the call. Video meetings have to be recorded in the desktop or mobile app, or uploaded afterwards as a recording — which leaves room for the classic “I forgot to hit record” failure.
• Diarization shines in small meetings: Hands-on reports consistently find that accuracy is strong with 3-4 speakers but degrades noticeably at 7 or more (these are not official Naver figures). Real-time speech recognition is on the 2026 roadmap for the second half of the year, but it remains a plan, not a shipped feature.

🔵 2) Daglo — an all-in-one AI platform that outgrew transcription

• It is not an STT app anymore: Launched in 2019 as one of Korea’s earliest speech-to-text services, the 2026 version of Daglo bills itself as an all-in-one AI platform under the slogan “every AI in the world, in one place.” Sitting on top of transcription you now get AI chat (ChatGPT, Perplexity, Claude and others), document analysis, and quiz and slide generation. That is overkill if all you want is meeting minutes — and a huge advantage if you are also studying or doing research.
• 14 languages, more than 3x Clova Note: Korean, English, Japanese, Chinese, German, Spanish, French, Italian, Russian, Vietnamese, Persian, Dutch, Hindi, and Thai — 14 languages in total (official blog, 6 March 2026). Against Clova Note’s four, the multilingual gap is stark.
• Strong on proper nouns and jargon: Hands-on reviews from secondary sources repeatedly report that recognition of proper nouns, technical terms, and brand names beats Clova Note. Daglo itself claims “98%+ accuracy under ideal recording conditions,” but that is a vendor self-report and should not be taken at face value.
• Recording directly in the mobile app is free and unlimited: Even on the free plan, recording directly through the app is unlimited; the caps apply to file and YouTube uploads (Free: 4 hrs/month, Pro: 45 hrs/month, Premium: unlimited). If your habit is pulling out your phone and hitting record in the room, Daglo feels the most generous of the five on a free plan.
• Video meetings are, if anything, its weak spot: Daglo has no auto-join bot either, and its own official guide says outright: “Recording may not work smoothly while wearing earphones or during video meetings; use direct recording, or record first and then upload the file for transcription” (Daglo official blog, 6 March 2026). So if Zoom and Teams calls dominate your week, you are forced down the “record, then upload” path — and uploads are exactly what the free plan caps at 4 hours a month. The unlimited-recording advantage largely evaporates for remote-first teams.
• Max length per session is not officially published: Daglo does not state anywhere public how long a single file can be. The official pricing page is script-rendered and yields no readable text, and the 2026 official guide gives only processing time (roughly 5-60 minutes for a one-hour file), never a ceiling. If you plan to hand it a half-day workshop, the only way to find out is to test a file close to your real length before you pay.
• Pivoting toward B2B and security: As of April 2026, its published B2B references include DB Life Insurance, Hancom, Daegu City Hall, Seoul National University Hospital, and KT SkyLife — all major Korean institutions — alongside 2.8 million cumulative hours of audio processed, 3.3 million cumulative transcriptions, and subscription revenue up more than 3x year over year. One detail to get right: ISO 27001 is in progress, not certified.

🟣 3) Otter.ai — the global standard, minus Korean

• The dealbreaker is the missing language: To repeat, because it matters: the title of Otter’s own help center article is “Transcribe conversations in English, Spanish, French, German, Japanese, or Chinese (Simplified).” Korean is not on that list. Adding Japanese got Otter into the Japanese market, but for Korean there is not even a published roadmap.
• The scale is still overwhelming: Industry tallies put it above 35 million users and one billion meetings transcribed, with ARR crossing $100 million (March 2025, per secondary sources). Some estimates have it processing more than 120 million meeting-minutes a year as the transcription layer under Zoom, Teams, and Google Meet.
• The 2026 direction is “note taker → knowledge engine”: With the April 2026 launch of the Conversational Knowledge Engine platform, Otter repositioned itself from a meeting-notes tool to enterprise knowledge infrastructure. The new lineup includes AI meeting workflows, advanced meeting templates, and an SDR Agent that qualifies leads, produces personalized video demos, and books meetings automatically.
• The MCP server is included on the free plan: The most practically interesting change of 2026 is that the Otter MCP server is available even on the free plan. On the other hand, “AI Chat with Gmail/Google Drive/Notion/Jira” is still marked Coming Soon.
• The real free-tier constraint is 30 minutes per session: Basic gives you 300 minutes a month, which looks identical to Clova Note — but you also hit a 30-minute-per-session ceiling and a lifetime limit of 3 file imports. That means you cannot drop a one-hour recurring meeting in as a single file. What that same free Basic tier does include, uniquely among these five, is the auto-join bot for Zoom, MS Teams, and Google Meet. Otter switches on at $0 a capability the two Korean products do not offer even on paid plans.

🟠 4) Notta — competing on language count and workflow

• 58 languages is exceptional coverage: Per the Pro plan description, Notta handles real-time transcription in 58 languages, Korean included (it runs a dedicated Korean transcription landing page). Its marketing also uses phrases like “100+ languages and dialects,” but the number varies by source — 58, 100+, 104 — so this article treats only the officially stated 58 as confirmed.
• The weakest free tier of the five: Free gives you 120 minutes a month with a 3-minute cap per session. Three minutes per session makes it a trial, not a meeting-notes tool. It is more accurate to think of Notta as “a service you pay for from day one” rather than “a service you try for free.”
• Pro is genuinely good value: Pro runs $13.99/month, or $97.99/year billed annually ($8.17/month effective), for 1,800 minutes a month and up to 5 hours per session. That is more than Otter Pro’s 1,200 minutes, at a lower price.
• The trap: real-time translation is billed separately: Translating a text transcript is included in Pro and Business, but live translation is a paid add-on. Single-language live translation is +$6/month billed annually (+$10/month monthly), and bilingual transcription plus translation is +$9/month annually (+$15/month monthly). If you sign up thinking “Notta does real-time translation,” your budget will be off.
• The 2026 additions are workflow-side: Per the official changelog, recent releases added weekly reports, multi-document support in Ask AI, an upgraded Notta Sales Agent, Slack Huddle recording and transcription (Notta Web), and YouTube video summaries from the Chrome extension. Slack Huddle support in particular is a real differentiator for huddle-centric teams of the kind covered in our team collaboration tools guide comparing Slack, Teams and Jandi.

⚫ 5) Whisper (on-device) — the only option where audio never leaves your machine

• In August 2026, the newest weights are still large-v3: Let us clear up the most common misconception first. There is no large-v4. The model list in the official GitHub repository contains only tiny, base, small, medium, large, and turbo, and the released weights remain large-v3 (November 2023) and large-v3-turbo (October 2024). Open-source Whisper has gone nearly two years without new weights.
• turbo is the practical default: Parameter counts run tiny 39M / base 74M / small 244M / medium 769M / large 1,550M / turbo 809M. Turbo shrinks the large-v3 decoder from 32 layers to 4, making it 2-5x faster (8x on some benchmarks) with only a small accuracy hit. Training data is 680,000 hours of labeled audio (117,000 hours across 96 non-English languages, plus 125,000 hours of translation data).
• It runs on an 8GB laptop: With whisper.cpp (the C/C++ port) or WhisperKit, you can run large-v3 on a laptop with 8GB of RAM. It costs nothing, has no usage cap, and your audio never leaves the device. It is the only fully on-device option among the five.
• Its biggest weakness is the lack of diarization: Whisper has no built-in speaker diarization. You have to bolt on a separate model such as pyannote, or use an app like MacWhisper. Given that the whole point of meeting minutes is “who said what,” that is a serious gap.
• MacWhisper is the pragmatic answer: If you are on a Mac, MacWhisper Pro (€59, roughly $69, one-time purchase, yours forever) is close to the correct answer. It includes the large-v3, turbo, and medium models, batch transcription, speaker diarization, real-time transcription from mic and system audio, YouTube URL transcription, and AI summaries — with transcription running on-device via whisper.cpp/WhisperKit. Cloud engines and AI post-processing are opt-in and use your own API key. Pro Max is $149 one-time and adds a commercial license plus AI chat over your transcripts. The fact that it is a one-time purchase rather than a subscription is decisive over a long horizon.
• Do not confuse this with the “Whisper API”: On 28-29 July 2026, OpenAI shipped gpt-transcribe (file transcription) and gpt-live-transcribe (real-time), replacing gpt-4o-transcribe and gpt-realtime-whisper respectively. Pricing is $0.0045/min for gpt-transcribe (down from $0.006/min) and $0.017/min for gpt-live-transcribe. But these are all closed-source cloud APIs, not successor weights for open-source Whisper. You cannot run them on-device.

3. Accuracy and Free-Tier Benchmark Showdown

The thing everyone actually wants from an AI meeting notes app comparison is accuracy. So let me be upfront before we start: no 2026 Korean-language accuracy benchmark exists that tests all five products under identical conditions. Any article declaring “the most accurate Korean transcription of 2026 is X” has nothing to stand on. This section presents only the metrics that can actually be verified, kept separate from one another.

[How many real meetings can you record for free — free-tier value ranking]
Whisper (local) : ⭐⭐⭐⭐⭐ (unlimited and free, but no speaker diarization)
Daglo           : ⭐⭐⭐⭐☆ (unlimited in-app recording + 4 hrs/month of uploads)
Clova Note      : ⭐⭐⭐⭐☆ (300 min/month, 600 with training consent / 180 min per file)
Otter           : ⭐⭐☆☆☆ (300 min/mo, 30 min per session + no Korean / but the bot auto-joins even on free)
Notta           : ⭐☆☆☆☆ (120 min/month + 3 min per session, effectively a demo)

📉 Whisper Korean accuracy: read CER, not WER

Whisper large-v3 posts a Korean CER of 5.27% (FLEURS benchmark, per 2026 Korean ASR analyses). The reason CER (character error rate) is the right metric here matters. As OpenAI explains in an official discussion, Korean frequently tolerates omitted spacing, and the Common Voice 15 and FLEURS labels themselves contain plenty of spacing errors and inconsistencies, which distorts word-level WER. That is why OpenAI uses CER instead of WER for six languages including Korean. If you see a source confidently quoting “Korean WER of X%,” a little skepticism is warranted.

There is one practical takeaway here. Korean and Japanese show unusually large performance gaps between model sizes. If you run Whisper locally and settle for small or base, your Korean output gets visibly worse. Use large-v3 or turbo as long as your RAM allows. For reference, OpenAI officially states that large-v3 reduced errors by 10-20% overall compared with large-v2.

⚠️ How to read vendor benchmarks

Korean CER leaderboards circulate freely online. For example, the Korean CER table published by STT vendor Soniox shows figures like Azure 1.21%, Soniox 1.25%, Speechmatics 1.4%, AWS 1.68%, Deepgram 1.71%, Google 2.84%, and OpenAI 3.24%. But Soniox’s own CER appears as both 1.25% and 4.3% on the same page, and neither the measurement date nor the dataset is disclosed. It is also worth remembering the table was built by a competitor.

A related table from the same source, which includes Korean services, lists NAVER CLOVA Speech at ₩1,200/hr (about $0.86/hr) with a CER of 9.09%. But that is CLOVA Speech, the developer API — not Clova Note. Using that table to conclude “Clova Note is inaccurate” is a complete misreading.

🥊 Clova Note vs Daglo head-to-head — but the data is from 2024

Just about the only press test putting the two services side by side under identical conditions is the Edaily hands-on column [It: Try It]. Comparing the same roughly one-minute video, spelling accuracy came out at 45.45% for Clova Note versus 33.33% for Daglo, but Daglo was more accurate at word recognition (Clova Note misheard “when I got the offer” as “when the senior arrived”). The reporter’s overall verdict was that “Daglo read more naturally.”

The catch: that article is dated 3 August 2024. It is two-year-old data, and in the interim Clova Note added automatic speaker identification while Daglo rebuilt its pricing from the ground up. As evidence of current performance it is plainly stale. Even so, the directional finding — that Daglo is stronger on proper nouns and technical vocabulary — keeps showing up in later secondary sources, so it remains useful as a signal of tendency.

4. Complete Pricing and Plan Comparison

[Real monthly cost for an individual user, as of August 2026]
Clova Note (personal) : $0                    — no paid plan exists; extra minutes cannot be bought
Daglo Pro             : KRW 14,900/mo (~$11)  — KRW 11,900/mo (~$8.50) effective, billed annually
Daglo Premium         : KRW 24,900/mo (~$18)  — KRW 16,580/mo (~$11.85) effective, billed annually
Otter Pro             : $16.99/user           — $8.33/user billed annually (no Korean support)
Notta Pro             : $13.99                — $8.17/mo effective, billed annually
MacWhisper Pro        : €59 one-time          — not a subscription; $0 thereafter

💳 Korean services, detailed pricing

There is one thing you absolutely need to know about Naver Works Clova Note. These prices are per company (per domain), not per seat. The member count is unlimited. Plenty of Korean blogs write it up as “KRW 20,000 per person per month,” and according to the official pricing page that is simply wrong. Many also list “Lite = 6,000 minutes,” when the official page says Lite 1,000 minutes / Team 6,000 minutes. For a 10-person team on Lite, that works out to KRW 2,000 (about $1.40) per person — a completely different cost structure. Annual contracts get up to 20% off, and if you run short you can buy an add-on of 200 minutes plus 10 summaries for KRW 5,000 (about $3.60).

🌏 International services, detailed pricing

Neither Otter nor Notta publishes an official Korean won price list. Billing is in USD, so exchange rates and foreign-transaction fees get added to your real cost. A lot of articles present a converted figure as if it were an “official Korean price” — no such price exists.

💸 Three hidden costs

First, Daglo’s credits are hard to feel. On 16 June 2025 Daglo introduced the Premium plan and shifted to credit-based billing. The problem is that there is no published conversion rate for “one hour of transcription = X credits.” So every article that tells you “1,000 free credits gets you N hours” is guessing. On top of that, one user’s measured analysis (6 April 2026) found each AI chat question burning roughly 387 credits on average, meaning you hit the credit ceiling long before the advertised “5,400 AI chats per month.” Run out and you top up at 3,200 credits for KRW 5,000 (about $3.60).

Second, Daglo Pro lost features. The overhaul actually narrowed Pro. AI chat and template-based summaries became unavailable on Pro, PDF analysis dropped from 2,000 pages a month to 1,000, and the custom glossary shrank from 1,000 entries to 500. If you want the AI features, you have to go Premium. Buy Pro based on an older review and it will not match your expectations.

Third, Notta’s real-time translation add-on. As noted above, live translation is not included in Pro or Business. Add bilingual transcription plus translation on a monthly plan and you are at $13.99 + $15 = about $29, which is nearly Business money. If multilingual meetings are why you picked Notta, budget for the add-on from the start.

For what it is worth, optimizing your total documentation spend means looking past the meeting-notes app to the note app that those transcripts eventually land in. We covered that in detail in our note-taking app guide comparing Notion, Obsidian and Apple Notes.

5. Final Recommendations by User Type

🎯 1) An individual professional with 1-2 Korean meetings a week, under an hour each

• Best choice: Clova Note (free)
• Why: 300 minutes a month covers five one-hour meetings. You also get 15 summaries a month, and it costs nothing. Just remember that unlocking 600 free minutes requires consenting to have your recordings used for AI training — if your meeting content is sensitive, staying at 300 is the better call.

🎯 2) A specialist recording meetings full of industry jargon, product names, and people’s names

• Best choice: Daglo Pro (KRW 14,900/month, ~$11; KRW 11,900, ~$8.50, billed annually)
• Why: Hands-on reviews consistently find it better than Clova Note at proper nouns and technical terms. With 45 hours of uploads a month, you have room to spare even at two hours of meetings a day. Just remember that AI chat and template summaries are not available on Pro.

🎯 3) A student or researcher who wants meetings, lectures, research, and document analysis in one app

• Best choice: Daglo Premium (KRW 24,900/month, ~$18; KRW 16,580, ~$11.85, billed annually)
• Why: Unlimited uploads, 4x processing speed, and AI chat, quiz generation, and document analysis all bundled into one platform. Credits burn fast, though, so if you use AI chat heavily, check your remaining balance regularly. Note also that there is no standing student discount — only seasonal back-to-school promotions.

🎯 4) A sales or international business rep meeting English-speaking clients and global teams daily

• Best choice: Otter Business ($30/user; $19.99/user billed annually)
• Why: Unlimited transcription, 4 hours per session, unlimited file imports, plus the SDR Agent that qualifies leads and books meetings automatically. But Korean meetings will not be transcribed, so you will absolutely need a second tool for domestic meetings.

🎯 5) A team with frequent meetings mixing Korean, English, Japanese, and Chinese

• Best choice: Notta Pro ($13.99/month; $8.17 billed annually)
• Why: Officially 58 languages of real-time transcription, with 1,800 minutes a month and 5 hours per session — the most generous limits in its price bracket. If you truly need live translation, price the add-on in advance. And if you want to raise the quality of your post-meeting translations, our AI translator guide comparing DeepL, Google and Papago is a useful companion read.

🎯 6) An organization where audio can never leave the building — contracts, HR, healthcare, legal

• Best choice: On-device Whisper — MacWhisper Pro (€59 one-time) on a Mac, WhisperX or Buzz on Windows and Linux
• Why: It is the only one of the five where audio never leaves your device. Clova Note, Daglo, Otter, and Notta all transmit to the cloud. On a Mac, MacWhisper Pro includes speaker diarization and is a one-time purchase rather than a subscription, so for any organization planning to use it three years or more it also wins on total cost.
• Windows and Linux have an answer too: Hospitals, legal teams, and HR departments mostly standardize on Windows, and MacWhisper is Mac-only — so the recommendation cannot stop there. The open-source WhisperX README lists “Multispeaker ASR using speaker diarization from pyannote-audio” as a headline feature and documents CUDA installation for both Windows and Linux, which means a fully local pipeline including diarization is buildable on Windows. If the command line is a barrier, Buzz ships installers for Windows, macOS, and Linux and describes itself as “Transcribe and translate audio offline on your personal computer.” The trade-off is that neither ends with a single payment the way MacWhisper does: you handle the Python environment and the model downloads yourself, so budget one person’s setup time. In a regulated industry that setup cost is usually cheap next to the risk of shipping audio off-premises.

6. Practical Tips and Common Mistakes

① Understand exactly what Clova Note’s free 600 minutes costs you. The trigger that takes you from 300 to 600 minutes is the “consent to collection and use of personal information (optional)” checkbox, and what it really means is allowing your recordings to be used to train Naver’s AI. If you are recording internal HR conversations or client contract negotiations, stopping at 300 minutes is the right choice. Conversely, for personal lecture notes or idea capture, 600 minutes is far more practical. You can change this setting at any time, so keeping separate accounts for different kinds of meetings is also a viable approach.

② The reset date differs between the personal and business products. For personal Clova Note, two explanations circulate side by side: quoted versions of Naver’s official help say the allowance resets at midnight (00:00) on the day after your sign-up date (sign up on the 15th, resets at 00:00 on the 16th each month), while other sources say “the 1st of each month.” Naver does not surface the rule prominently in the product, which is why the confusion persists — so on a personal account, rather than trusting either explanation, watch for one cycle when your remaining minutes actually come back. The business product, by contrast, is settled: the official Naver Works Clova Note pricing page states that the conversion-time quota “is renewed on the 1st of each month” and that “any unused conversion time remaining in the current month does not carry over to the next month.” So the 1st-of-the-month reset with no carry-over is official for company accounts; it is the personal account that needs checking. Either way, if long meetings cluster at month’s end, confirm your reset point before scheduling them. And on the personal tier it matters especially because once you hit the cap, there is no way to buy more minutes.

③ The per-session limit bites before the monthly cap does. The most common beginner mistake is paying based on the monthly cap alone. Otter Basic gives you 300 minutes a month but only 30 minutes per session; Notta Free gives you 120 minutes a month but only 3 minutes per session. If you need to capture a two-hour workshop, your options are Clova Note (180 min), Otter Business (4 hrs), or Notta Pro (5 hrs). Daglo can be neither included in nor excluded from that list, because it does not publish a per-session maximum anywhere. If you settle on Daglo, run a file close to your real meeting length through it and establish the ceiling yourself before you trust it with a long session — for the two personas this article recommends Daglo to (jargon-heavy professionals, students and researchers), that test comes before the payment. If long meetings are routine, getting into the habit of pre-splitting files into 30-60 minute chunks also helps.

④ Adjust your diarization strategy to headcount. Per hands-on reports, Clova Note is accurate with 3-4 speakers and degrades at 7 or more. For larger meetings, running a “roll call” where everyone says their name in the first 10 seconds makes it far easier to match speakers during cleanup. With Daglo you must enable [Speaker labels] before running transcription — you cannot switch it on afterward, so check before you record.

⑤ If you use Whisper, do not compromise on model size. Korean shows an unusually large performance gap across model sizes. In the reference benchmarks, the 0.6B-class model landed at CER 7.57% while the 1.7B-class hit 4.90%, and Whisper large-v3 came in at 5.27%. If speed is the problem, use turbo (809M) rather than dropping to small. It cuts the large-v3 decoder from 32 layers to 4, making it 2-5x faster with minimal accuracy loss. And since Whisper alone cannot do diarization, plan from the outset to either use an app like MacWhisper that bundles it or bolt on pyannote.

⑥ With Daglo, “recording in the app” and “uploading a file” cost different amounts. Even on the free plan, recording directly in the mobile app is unlimited, but file and YouTube URL uploads are capped at 4 hours a month. So leaving your phone recording in the meeting room is effectively infinite free usage, while uploading Zoom recordings after the fact will drain your quota fast. Simply shifting your workflow toward in-app recording can postpone a paid upgrade for a long time.

⑦ Decide your exit route before you hit the cap. Personal Clova Note — this article’s default recommendation — has no escape hatch. Once the allowance is gone you cannot buy minutes, so the only remaining choices are “wait until next month” and “move.” Headcount decides which way you go. Working alone with heavy uploads? Daglo Pro (14,900 KRW/month, 45 hours of uploads) is the closest replacement. Running a team with several accounts? Naver Works Clova Note Lite (20,000 KRW/month, 1,000 minutes) wins, because Lite is billed per domain rather than per person: past three or four people the per-head cost drops below Daglo Pro, and you can top up with a 5,000 KRW add-on for 200 minutes plus 10 summaries. If instead your problem is that meetings are mostly remote and you need a bot, neither Korean product solves it — splitting tools (Otter for English calls, Notta for multilingual ones) is the realistic answer. Before you move, check three things by hand: what formats you can get your existing notes out in, whether you can export many at once, and whether past notes stay readable after you cancel a paid plan. None of the five documents these publicly, which is why this article will not put numbers on them. Exporting one or two notes for real is the only way to know — and checking that result against where your transcripts ultimately need to go (issue tracker, note app, team channel) lets you price the whole move in one pass.

⑧ Judge security by where processing happens, not by marketing copy. In practice, this is the final gate in any AI meeting notes app comparison. Through 2026, competition in the Korean market is shifting from accuracy toward security. That said, Daglo’s ISO 27001 is in progress, not certified (as of April 2026), and for Daglo, Otter, and Notta there is no publicly verifiable primary source on whether voice data is used for AI training or on retention policy. The only certainties are that all four services transmit audio to the cloud and that only locally run Whisper transmits nothing. In a regulated industry, that one line is the entire decision.

7. Frequently Asked Questions (FAQ)

Q. When will Clova Note start charging?

As of August 2026, the consumer version of Clova Note has no paid plan at all. Naver’s official help text states plainly: “Paid features are not currently supported, so additional usage time cannot be purchased.” No official announcement of a timeline for monetization has surfaced. That said, it is worth noting that the consumer product still carries the “beta” label while Naver Works Clova Note operates separately as a paid enterprise product.

Q. Can Otter transcribe a meeting held in Korean?

No. Otter’s official help center lists six supported languages — English, Spanish, French, German, Japanese, and Chinese (Simplified) — and Korean is not among them. This applies to every plan. Japanese was added in 2026, but for Korean there is not even a published roadmap. If your meetings are primarily in Korean, dropping Otter from consideration is the correct call.

Q. Which is more accurate, Clova Note or Daglo?

As of 2026, there is no credible benchmark comparing the two under identical conditions. In Edaily’s August 2024 comparison test, Clova Note won on spelling accuracy (45.45% vs 33.33%) while Daglo won on word recognition, and the reporter’s overall verdict favored Daglo. But that is two-year-old data, and both products have changed substantially since. Directionally, reviews consistently suggest Daglo for meetings heavy on proper nouns and jargon, and Clova Note as a solid default for ordinary Korean conversation.

Q. How many hours can I transcribe on Daglo’s free plan?

Recording directly in the mobile app is unlimited, while file and YouTube uploads are capped at 4 hours a month. You also get 1,000 credits a month, but because there is no published conversion rate for “one hour of transcription = X credits,” calculating exact hours from the credit balance is impossible. If an article gives you a specific number of hours, treat it as an estimate.

Q. When is Whisper large-v4 coming out?

There is no large-v4. As of August 2026, the newest publicly released OpenAI Whisper weights are large-v3 (November 2023) and large-v3-turbo (October 2024), and the official repository’s model list contains only tiny, base, small, medium, large, and turbo. The gpt-transcribe and gpt-live-transcribe models released in July 2026 are not successors to open-source Whisper — they are closed-source cloud APIs and cannot be run on-device.

Q. Is Naver Works Clova Note KRW 20,000 per person?

No. According to the official pricing page, billing is per company (per domain), and the number of members is unlimited. Lite at KRW 20,000/month (about $14) is the price for the entire team. Many Korean blogs incorrectly write it as “KRW 20,000 per person per month,” and the “Lite = 6,000 minutes” figure is also wrong. The official numbers are Lite 1,000 minutes / Team 6,000 minutes. Annual contracts get up to 20% off.

Q. Which AI meeting notes app can I use free for the longest?

If you have the hardware, running Whisper locally is unlimited and free, and nothing else comes close. If installing and configuring software is too much, Daglo’s unlimited in-app recording is the realistic alternative, followed by Clova Note (300 minutes a month, 600 with consent). Otter Basic gives you 300 minutes a month but is hobbled by the 30-minute session cap and the lack of Korean, and Notta Free is hobbled by its 3-minute session cap.

Q. Can I stop my meeting audio from being used for AI training?

With Clova Note, leaving the “consent to collection and use of personal information (optional)” box unchecked means you do not consent to training use — at the cost of being limited to 300 minutes a month. For Daglo, Otter, and Notta, training use and retention policies cannot be confirmed from publicly available primary sources, so nothing definitive can be said; check each company’s current privacy policy directly if it matters to you. The only way to block it with certainty is running Whisper locally, so the audio never leaves your device in the first place.

Q. Is there a meeting notes app with real-time interpretation?

Notta offers real-time translation, but it is a separate add-on not included in Pro or Business. Single-language live translation is +$6/month billed annually (+$10/month monthly), and bilingual transcription plus translation is +$9/month annually (+$15/month monthly). Translating a text transcript after the fact is included in Pro and Business, so start by deciding whether you genuinely need it live. Clova Note has real-time speech recognition on its roadmap for the second half of 2026, but it remains a plan.

8. Conclusion: In 2026, Compare AI Meeting Notes Apps in This Order — Language, Then Security, Then Price

Compress this AI meeting notes app comparison into one sentence and it reads like this: if your meetings are primarily in Korean, your only candidates are Clova Note, Daglo, Notta, and Whisper — start free with Clova Note, go Daglo for jargon-heavy work, Notta for multilingual meetings, and Whisper when security comes first. Otter is the global heavyweight, but the single fact that it cannot transcribe Korean removes it from consideration for meetings held in Korea.

The second conclusion is that you have to read the conditions, not the numbers on the price list. Clova Note’s free 600 minutes comes at the price of consenting to AI training, Daglo Pro can no longer use AI chat or template summaries after the overhaul, Notta’s live translation is a separate purchase, and Naver Works Clova Note bills per domain rather than per seat. Knowing just those four things puts you ahead of most of the badly researched comparisons out there.

Third, the market data out of Korea tells a story worth noting. Clova Note grew to 6.6 million sign-ups but saw MAU fall for three straight months, while Daglo — with a third of the registered users — has closed to within 71% on MAU and more than tripled subscription revenue. That is the difference between “I signed up because it was free” and “I pay for it and use it every day.” Ask yourself the same question when choosing a tool. The real criterion is not the size of the free tier but whether you will actually use it daily.

A meeting-notes tool is infrastructure you live with for at least a year once you commit. Do not let the size of a free tier decide it for you. Start by settling what language your meetings are in, how many people are in the room, and whether that audio is allowed to leave your building. Once those three are settled, the table above narrows to almost exactly one answer. 🎙️✨
