Transcribe audio without sending it to a server
An interview under embargo or a client call under NDA shouldn't visit a transcription company's servers.
GigAI Video Intelligence runs OpenAI's Whisper model inside your browser via transformers.js, so the recording is transcribed on your own device and never uploaded. Otter, Rev and Fireflies all require upload; this doesn't. Free, no account - after the one-time model download it even works offline.

How to fix it
Follow these steps and you'll have it sorted in a couple of minutes.
- 1
Drop the recording
Audio or video - decoding and transcription both happen locally.
- 2
Pick a model size
Fast English (42 MB) for quick drafts; the multilingual model for accents and other languages. Downloads once, then caches.
- 3
Edit and export
Fix names inline, label speakers, then export TXT, Markdown, SRT or VTT.
- Assuming 'private' cloud transcription means unprocessed - upload IS processing on someone else's machine; read their retention terms.
- Using the large model for a clear English recording - the small model is dramatically faster and usually enough.
