Voice Rack
声音档案馆

Ask your recordings. Offline. A private archive for everything you have ever recorded — meetings, lectures, voice notes, interviews — with transcription, tagging, search and summaries that run entirely on your Mac.

Your recordings stay yours

Nothing is uploaded, ever. The transcription engine and the language model both run locally, on Apple Silicon — the same machine the recordings live on. Ask a question about a two-hour meeting on a plane with WiFi off; it works exactly the same.

An archive, not a pile of files

Import MP3 recordings into a library it manages — organized by date, deduplicated, compressed with the system encoder so years of audio fit. Transcription runs as a queue you can pause and resume; on Apple Silicon it runs at tens of times real time.

Ask, don't scrub

Search across every file at once. Ask a question and get an answer with clickable timestamps that jump to the exact moment in the audio — citations, not summaries you have to trust. Long recordings switch automatically to retrieval so a three-hour file answers as readily as a three-minute one.

Honest by design

Auto-extracted tags are suggestions until you confirm them. Cleaned-up transcripts keep the original language and guard every number — anything the model cannot carry over verbatim is kept in the original and flagged, never silently dropped.

Status: in development. One-time purchase, no subscription — your archive should not stop working when you stop paying.

Built on Tempo9, the same local inference engine behind everything on this site.
