HumlaA meeting notes app built for the Mac
Not a cross-platform shell. Humla uses native macOS audio capture and runs Whisper on Apple Silicon.
Free · Open source · macOS 13+ (Apple Silicon)
Humla is built for one platform and does it properly. It captures your mic with AVAudioEngine and the call's audio with ScreenCaptureKit, transcribes with Whisper on your Mac's GPU, and labels speakers with on-device models — all without a bot or an account.
Native audio capture
AVAudioEngine for your mic, ScreenCaptureKit for system audio — captured as two clean, separate streams.
Whisper on Apple Silicon
On-device transcription runs on your Mac's GPU via Metal. Fast, free, and offline after a one-time model download.
On-device speaker labels
Diarization runs locally with CoreML, so you get colour-coded “who said what” without uploading a thing.
No bot, records your Mac
Nothing joins the call. Humla records your own machine, so remote and in-person meetings both work.
Signed & notarised
A proper Developer ID build that opens cleanly and updates itself.
Apple Silicon, macOS 13+
Built for modern Macs. Windows and Intel aren't supported today — star the repo to vote.
See a meeting become a note.
New note, record, summary — that's the whole workflow. The cleanup afterwards is none, on a five-minute meeting or an hour-long one.
