Question 1

How do I add captions or subtitles to a video?

Accepted Answer

Open AI Video Captions and upload your video. On-device AI transcribes the audio into a transcript you can edit, you choose the caption font and style, and then you download the video with the captions burned in — or export an SRT or VTT subtitle file.

Question 2

Does it work for Swahili?

Accepted Answer

Yes. It captures Swahili and English, including a natural mix of the two, and can translate the captions into English and other languages.

Question 3

Is my video uploaded anywhere?

Accepted Answer

No. The transcription runs entirely in your browser using on-device AI, so the audio and video never leave your device — good for private or unreleased footage.

Question 4

Can I change the caption size and font?

Accepted Answer

Yes. You can pick the font and adjust the caption size and style, then see it live on the video before you burn the captions in and download.
