On-device transcription for Mac

Your calls, transcribed on your Mac.

Letopis records meetings and audio, then transcribes them locally with speaker labels and timecodes. Nothing leaves your Mac.

Download for Mac (.dmg) How it works

The direct download is notarized, updates itself, and includes the GigaAM v3 engine for Russian, the letopis command-line tool and an MCP server for AI assistants (Claude Code, Claude Desktop). Free for personal use. Requires macOS 26+ on Apple Silicon.

Privacy

Private by design.

Recording, transcription, and speaker diarization run on your Mac with on-device models. The only thing Letopis downloads is the models it runs.

  • No cloud upload of audio or transcripts
  • No account and no sign-in
  • No analytics or tracking
  • Recordings stay in a folder you choose
  • Optional on-device redaction of personal data before you share (best-effort)

Letopis transcribing on a Mac
Transcript viewer

Read it back, speaker by speaker.

Every line has a timecode and a speaker. Play the audio alongside, edit, rename speakers, export.

Recording from the menu bar

Record from the menu bar.

One click starts the recording. Recent transcripts and import are in the same menu.

Capture settings

Mic and system, two clean tracks.

Pre-roll and an end-of-call watchdog capture the whole call; echo cleanup keeps the audio clear.

Onboarding model setup

Ready from the first launch.

The Whisper and speaker models are prepared once and run on the Neural Engine.

Transcription settings

Two engines, on-device.

GigaAM v3 for Russian - faster, with native punctuation; Whisper Podlodka Turbo for Russian and English. Personal data can be redacted before you share, all on the Mac.

General settings and Claude integration

Works with Claude.

An MCP server lets Claude Code and Claude Desktop read your transcripts. Plus global shortcuts and a recordings folder of your choice.

Does my audio go to the cloud?
No. Recording and transcription happen on your Mac. The only network request Letopis makes is downloading the speech model.
Which Macs are supported?
Apple Silicon Macs on macOS 26. The transcription model runs on the Neural Engine.
What languages can it transcribe?
English and Russian, with automatic language detection. The interface is available in both.
Where are my recordings stored?
In a folder you choose on your Mac. You can change it in Settings.
Can AI assistants work with Letopis?
Yes. Letopis includes an MCP server: Claude Code and Claude Desktop can transcribe audio or video files and read your transcript library. Set it up from Settings; everything still runs on your Mac.
