Free private meeting transcription app for macOS
Biscotti transcribes Mac meetings fully on device
scosman/Biscotti is a free macOS app that records meetings and turns them into speaker-labeled transcripts and summaries. All processing runs locally, so no audio leaves the Mac.
Privacy and how it works
Biscotti records your microphone and your Mac system audio from any meeting app, then transcribes on device with speech recognition that produces a speaker-labeled transcript powered by Apple Silicon. Local AI writes a summary, pulls out action items, and figures out speaker names. The README states the app works completely offline after the models are downloaded, and that audio and transcripts never leave the Mac.
Features for daily use
The app is free with no account and no subscription, and it does not join a call as a bot, so other participants are not notified. It works with Zoom, Microsoft Teams, Google Meet, FaceTime, Slack huddles, and even in-person conversations through the microphone. It is calendar aware, can auto stop when a call ends, isolates voices into separate clean channels, and lets you jot markdown notes linked to the moment they happened.
Requirements and stack
Biscotti needs a Mac with Apple Silicon, an M1 or later, running macOS 15 Sequoia or newer, with 16 GB of RAM recommended. Under the hood, transcription uses Whisper V3 Turbo through WhisperKit, speaker identification uses Pyannote through SpeakerKit, and the language model is Google Gemma 4 run on llama.cpp. The combination keeps every processing step on the user machine.
Editorial conclusion
The app is built as a native macOS program and is distributed under the PolyForm Perimeter License 1.0.1.
