Interview transcripts with speaker labels — the audio never leaves your Mac.

Can journalists transcribe interviews privately on a Mac?

Yes. Lesskeys transcribes on your Mac using Apple Silicon's GPU, so an interview recording is never uploaded to a transcription service. There's no account, no cloud queue, and it works offline. For reporting where a source's identity or a recording's contents must stay protected, keeping the audio on your own machine removes an entire category of exposure.

Why "on your device" matters for source protection

Cloud transcription tools send your recording to a third-party server to process it. That means a copy of a sensitive interview exists somewhere you don't control, subject to that company's retention, security, and legal obligations. Lesskeys keeps the recording and the transcript on your device — a practical safeguard, not a promise you have to take on trust.

What you get

A working setup for interview days

  1. Record or import — capture a call locally (Zoom, Meet, phone on speaker) or drop in a field recording. Audio and video files both work.
  2. Transcribe on your Mac — the interview is transcribed and speaker-labeled on-device. A two-hour recording never touches a server.
  3. Name the voices — label "Speaker 1" as your source once; recurring voices can be recognized across recordings, locally.
  4. Pull quotes with confidence — click any line to jump the synced player to that exact moment and verify the quote against the audio before it goes in the piece.
