Open source

Meeting notes you can actually audit

Humla is MIT-licensed and public. The “nothing leaves your Mac” promise isn't a policy — it's code you can read.

  • Free, no account
  • Open source, MIT
  • Apple Silicon, macOS 13 or later

Open where it counts

Plenty of note-takers are open source now. What sets Humla apart isn't the licence — it's what the licence lets you verify: a macOS-native app that captures your mic and the call as two separate streams, labels who said what on-device, and keeps every recording on your disk.

MIT licensed

The whole macOS app is public under the MIT licence. Read it, fork it, build your own.

Auditable privacy

“Nothing leaves your Mac” is a claim you can check — the on-device path is right there in the source.

No account needed

Download and record. The app has no sign-up, and Humla Cloud is only there for teams that want sync.

Bring your own key

Use your own OpenAI, Deepgram, or Groq key — or on-device Whisper and no key at all.

macOS-native, not a port

Built on Tauri with Swift capture sidecars, so it feels like a Mac app rather than a cross-platform shell.

Two streams + real diarization

Mic and system audio are kept separate end to end, so speaker labels hold up where single-stream tools blur together.

FAQ

Questions and answers

Is Humla really open source?

Yes — the macOS app is MIT-licensed and public on GitHub. You can read every line, including the on-device transcription path.

What's the catch if it's free and open source?

There isn't one for the app. Only the optional team sync, Humla Cloud, is paid. Everything else in the app is free.

How is Humla different from other open-source notetakers?

Most are cross-platform. Humla focuses on macOS-native polish, two-stream mic + system capture, and on-device speaker labels — not just being open source.
