Frequently Asked Questions
Is the transcription really private?
Yes. The AI model runs as WebAssembly inside your browser tab — the audio is processed on your machine and never sent to any server.
Which languages does transcription support?
The on-device model handles the major languages with good accuracy; technical terms and heavy accents may need manual fixes on the timeline.
Can I burn the subtitles into the video?
Pair the exported SRT with the free video tools to burn captions in locally.
