Whisper vs Otter.ai
Home › Guides · Last checked 2026-10-16 · Facts verified from each project's docs unless marked tested
Whisper is free, MIT-licensed speech-to-text that runs on your own computer and exports SRT captions. Otter.ai is a cloud service. Whisper wins on cost and privacy; Otter wins on convenience. Buzz gives Whisper a desktop GUI if you don't want the command line.

Buzz: Whisper for non-developers
Buzz is a desktop app for Whisper transcription (MIT). It's local only, so speed depends on your machine.
Who should stay on Otter
If you want a hosted service with no install and don't mind uploading audio, Otter is simpler. If privacy or cost matters more, use Whisper.

FAQ
Is Whisper as accurate as Otter?
We haven't tested both side by side and won't guess. Accuracy depends on the Whisper model size, audio quality and language.
Is Whisper free for commercial use?
Whisper's code is MIT-licensed, which allows commercial use.
How slow is Whisper on a laptop CPU?
Large Whisper models are slow on CPU. Smaller models are faster but less accurate. A GPU helps a lot.
Does Otter have a free plan?
Otter's plans and limits change. Check otter.ai/pricing for the current free-plan limits.
