   3) Replace `Body` with the transcript, set `{{Transcript}}`, and prepend the original media path plus a `Transcript:` section in the command prompt so models see both.
   4) Continue through the normal auto-reply pipeline (templating, sessions, Pi command).
 - **Verbose logging**: In `--verbose`, we log when transcription runs and when the transcript replaces the body.

 ## Notes & limits
-- We don’t ship a transcriber; you opt in with any CLI that prints text to stdout (Whisper cloud, whisper.cpp, vosk, Deepgram, etc.).
+- We don’t ship a transcriber; you opt in with the Whisper CLI on your PATH.
 - Size guard: inbound audio must be ≤5 MB (matches the temp media store and transcript pipeline).
 - Outbound caps: web send supports audio/voice up to 16 MB (sent as a voice note with `ptt: true`).
 - If transcription fails, we fall back to the original body/media note; replies still go through.
