FAQ
Questions, answered
Is it really free?
Yes. Automatic captions in the original language are free, with no watermark and no signup wall just to try it. Translation to other languages is a paid add-on when you need it.
Do you add a watermark to my video?
Never. Your exported video is pixel-clean — same resolution, frame rate, and audio as your source, with only your captions burned in.
How accurate are the captions?
We use state-of-the-art speech recognition with word-level timing. Accuracy is high across accents and noisy audio, and you can fix anything in the editor in seconds.
Can I edit the captions?
Absolutely. There's a full browser editor: fix text, drag captions on a waveform timeline to retime, reposition them on the video, restyle, and undo/redo. What you see is exactly what exports.
Which languages do you support?
Roughly 200. Caption in the spoken language for free, then translate to nearly any language — including non-Latin scripts like Hindi, Arabic, Chinese, and Japanese, rendered with the correct fonts.
What video formats can I upload?
Standard video files from your phone or editor. Upload a clip, and we take care of extracting audio, transcribing, and rendering the captioned result.
