How does AI transcription work without uploading my video?

CalmClip runs the Whisper speech recognition model locally in your browser via WebAssembly. The AI model downloads once and runs entirely on your device, so your audio never leaves your machine.

Does the transcription send audio to a server?

What languages does Whisper support?

Whisper supports dozens of languages. It detects the language automatically and transcribes in it.

Whisper produces professional-grade accuracy for clear speech in most languages. Accuracy is reduced by heavy accents, background noise, or very fast speech.

Does transcription require Pro?

Can I edit the transcript?

Yes. Every word is editable in the caption editor. You can fix names, technical terms, and anything the model missed.

Does the Whisper model need to be downloaded each time?
