Important: consent and recording laws still apply
Recording a meeting without a visible bot does not remove the need to tell participants and respect local recording laws. Use these tools with the consent of the people on your calls.

Best Otter.ai alternatives at a glance
| Alternative | Best for | License |
|---|---|---|
| Meetily | Local transcription and summaries on macOS and Windows | MIT |
| Anarlog | Meeting notepad with local files (enterprise code exists) | MIT core + enterprise |
| Minutes | Markdown transcripts that AI agents can query | MIT |
| Prismical | Free note taker for Mac and Windows (very young) | MIT |
How we chose these Otter.ai alternatives
We looked for open-source tools that overlap with Otter.ai's core: recording meetings, transcribing speech, and producing summaries and action items. We verified each project's license, recent activity, stars, and platforms in its repository. Otter joins calls as a bot and stores recordings in its cloud, so we compare tools that capture system audio and process it locally. See our methodology for the full criteria.
Closest to Otter.ai
Meetily is the most popular: it records system audio without a bot, transcribes locally with Whisper or Parakeet models, and generates structured summaries with local or cloud models. Anarlog is a meeting notepad that turns rough notes into editable summaries, with audio, transcripts, and notes stored as local files.
Important: paid tiers and enterprise code
Meetily's Community Edition is MIT, with a Pro tier at $10 per user per month and separate Enterprise plans, and cloud summary options send data off your device if you choose them. Anarlog's community application is MIT, but its repository also contains an enterprise license directory. Cloud AI in these tools is optional and needs your own API keys.
Developer-oriented options
Minutes is an MIT local recorder using whisper.cpp that saves transcripts as Markdown and exposes MCP tools so AI agents can query them, though some workflows are specific to macOS. Prismical is an MIT note taker for Mac and Windows with iOS and Android listed as coming soon.
License details
Meetily, Anarlog's community application, Minutes, and Prismical are MIT. OpenAlternative lists Anarlog as GPL, but the project says it moved to MIT in April 2026.
Maintenance status
Anarlog, Minutes, and Prismical had commits within days of this update. Meetily's last commit was in September 2026, and Prismical is very young with about 100 stars.
Why look for a Otter.ai alternative?
Otter.ai is a proprietary cloud service that joins your calls as a bot, stores recordings and transcripts on its servers, and limits transcription minutes and features by plan. Open-source alternatives record system audio without a bot, transcribe locally, keep files on your own device, and avoid per-minute limits, at the cost of local compute and less polished collaboration.
