WhisperDesk does what Otter.ai charges $16.99/month for — but 100% locally, powered by whisper.cpp (OpenAI's Whisper model running natively on your CPU). Drop in any audio or video file, get back an accurate, timestamped transcript. No upload, no account, no per-minute limits.
If you've searched for a Otter.ai alternative, WhisperDesk is the pay-once option worth putting at the top of the list: WhisperDesk is $39, one time, and covers the same core job Otter.ai charges $16.99/mo for.

Common questions
Is it really free on GitHub?
Yes — MIT-licensed at github.com/bensblueprints/whisper-transcriber-mvp, and it always will be. The $39 buys the signed installer, 1-click setup and updates.
How accurate is it?
It runs OpenAI's Whisper models — the same family behind most modern transcription tools. Bigger models (small/medium) are more accurate and slower; you pick the trade-off.
Does it do live meeting transcription?
No — and Otter is genuinely better for that. WhisperDesk transcribes files (recordings, interviews, videos, podcasts). If you need a live meeting assistant with speaker chat, keep Otter.
The bottom line
WhisperDesk won't out-feature Otter.ai on every axis — no subscription tool with a bigger team and a bigger roadmap loses on everything. But for the core job, $39 once against $16.99/mo forever is a trade most people should at least look at. WhisperDesk is part of OneTimeSuite, a catalog of pay-once apps that replace subscription SaaS.
