Meeting transcription & summaries, 100% on your Mac. Record, transcribe, tell speakers apart and get a clean summary, without a single byte leaving your machine.
macOS 13+ · Apple Silicon · v0.1.0 · free
Runs entirely on-device
Transcription, diarization and summaries all happen locally. Your audio never leaves your Mac and works fully offline.
Knows who said what
Speaker diarization powered by pyannote, with persistent voiceprints so recurring speakers are recognized across meetings.
Summaries that write themselves
A local LLM drafts a structured summary in the meeting's own language, weighted by the live notes you take.
Live notes while you listen
Jot bullets during the call. They stay in sync with the transcript and strongly steer the final summary.
Powered by best-in-class open models
State-of-the-art speech and language models, downloaded once and run entirely on your Mac. No API keys, no cloud inference.
Your meetings stay yours
No cloud, no account, no telemetry. Audio, transcripts and summaries are stored only on your Mac. Delete the app and everything is gone.
