What each one is
faster-whisper
faster-whisper reimplements Whisper on CTranslate2 for dramatically faster inference and lower memory use, with the same accuracy.
- Up to several times faster than vanilla Whisper
- Much lower memory footprint
- Same accuracy as the original model
unWarp
unWarp is a hosted service that turns voice memos and calls into searchable notes with a summary and action items; it runs in the browser, and calls are recorded by its Windows and macOS desktop app. Personal is €10/month, teams €8/seat, 14-day trial. Note before using it: nothing joins the call as a visible participant, so other people are not notified of the recording, and consent law, employer policy and platform terms still apply.
- Call audio is recorded by the desktop app on Windows and macOS, not by a meeting bot.
- Each note has a summary, action items with dates, a searchable transcript and the audio.
- Notes are stored in Frankfurt; voice audio is deleted in an hour, call audio in 30 days.
