Swiss German transcription for Zoom and Teams meetings on Mac

lautli is a free menu-bar app for macOS. It listens to your Zoom or Microsoft Teams meeting, transcribes the Swiss German (Schweizerdeutsch) live, and writes a Standard German transcript and summary. Everything runs on your Mac.

Download for macOS

Apple Silicon (M1 or newer), macOS 15 or newer. About 7 GB of free disk space for the first launch.

What it does

Swiss German speech to text. Dialect speech becomes readable text, live, while the meeting runs.
Standard German output. You get a Hochdeutsch transcript as a Markdown file in ~/Documents/lautli/.
Meeting notes. A summary with decisions, tasks and open questions, written by Apple's on-device model on macOS 26 or newer with Apple Intelligence.
Starts by itself. It detects Zoom and Teams meetings and shows its state in the menu bar.
English and German interface.

Private by design

Speech recognition runs offline on your Mac. Audio is converted to text in memory and never saved. There is no telemetry and nothing is uploaded. That makes lautli a fit for confidential meetings where cloud transcription is not an option. See the privacy policy.

How it works

Download the DMG, drag lautli to Applications and open it.
On first launch it downloads the speech model once (about 4 GB) and explains each permission before macOS asks.
Join a Zoom or Teams meeting. lautli starts listening and the transcript appears live.
When the meeting ends, open the transcript and notes from the menu bar.

Frequently asked questions

How do I transcribe Swiss German in Zoom or Teams?

Install lautli on an Apple Silicon Mac. It notices when a Zoom or Microsoft Teams meeting starts and transcribes the Swiss German speech live, then saves a Standard German transcript to your Documents folder.

Does lautli send my meeting audio to the cloud?

No. Speech recognition runs on your Mac, audio is never saved, and the app has no telemetry. The only network use is the one-time download of the runtime and speech model on first launch.

Which Macs and macOS versions does lautli support?

Apple Silicon Macs (M1 or newer) on macOS 15 or newer. Intel Macs are not supported. Standard German meeting notes need macOS 26 or newer with Apple Intelligence turned on. Without it you still get the full transcript.

Is lautli free?

Yes. You can download it from GitHub at no cost.

Early release. The model has been tested on synthetic Standard German, not yet on real Swiss German meetings or real Zoom and Teams calls. Review transcripts before you rely on them. Use headphones: without echo cancellation, speakers can make lines appear twice. Transcribing a conversation can require everyone's consent, so tell participants.
