Notta vs Otter.ai: Free Minutes, Languages, File Limits and Privacy
Data checked:
Both tools transcribe live meetings and uploaded files, and both run in a browser and on phones. People choose between them over four things: the shape of the free plan, language coverage, how long a single recording can be, and what happens to their recordings afterwards.
- Free plan. Notta gives 120 minutes a month, but only the first 3 minutes of each recording are transcribed, and downloading transcripts needs a paid plan. Otter.ai gives 300 minutes a month with a 30-minute cap per conversation and only 3 file imports in total; the free plan exports TXT only.
- Price. Notta Pro is $13.49 a month, or $8.17 billed yearly, with 1,800 minutes a month and recordings up to 5 hours. Otter Pro is $16.99 a month, or $8.33 billed yearly, with 1,200 minutes a month, 90-minute conversations and 10 file imports a month. Otter Business ($30 a month, or $19.99 billed yearly) extends conversations to 4 hours.
- Languages. Notta says it transcribes 58 languages, including Japanese and Mandarin; one of its tool pages claims 90+. Otter’s pricing page lists 6: English, Spanish, French, German, Japanese and Chinese.
- Files. Notta’s paid plans take recordings up to 5 hours, with uploads up to 1 GB of audio or 10 GB of video. Otter’s caps are 30 minutes (Basic), 90 minutes (Pro) and 4 hours (Business).
- Meetings and API. Notta’s bot joins Zoom, Google Meet, Teams and Webex; Otter covers Zoom, Meet and Teams. Otter lists API access on Enterprise; Notta’s API status was not verified.
- Privacy. Notta’s privacy policy does not say whether recordings train AI; its Japanese pricing page lists “no AI training” (AI学習なし) as an Enterprise feature. Otter’s policy says it trains its AI on de-identified audio and transcriptions and describes no opt-out.

Which to choose
- Choose Notta if your meetings or files include Japanese or Mandarin, if you need recordings up to 5 hours long, or if you need a Webex bot.
- Choose Otter if a fixed 300 free minutes a month fits meetings under 30 minutes, if you want the cheapest Business plan that allows 4-hour conversations, or if you need the Otter API on Enterprise.
- Neither is a good free tool for files: Notta stops at 3 minutes a recording and Otter at 3 imports in total. For free file transcription, see free transcription software.
