FAQ
Are my videos uploaded to caption them?+
No. Transcription and captioning run entirely in your browser on your device. There is no upload endpoint.
Is there a watermark or a length limit?+
No watermark, and you're limited only by your device's memory — not an upload cap.
Do I need an account?+
No account required to caption or to download your video.
What languages are supported?+
Captions are generated in the spoken language of your clip (it transcribes, not translates).
