  1. [01]

    drop in a video

    MP4 or MOV, straight from your phone. Vertical videos stay vertical.

  2. [02]

    check the words

    Every word is written out with its timing. Click a word to fix it, then pick a caption style.

  3. [03]

    export and post

    Get an MP4 with the captions burned in and your sound untouched. SRT and VTT too.

[privacy promise]

your video never leaves your computer.

There is no upload button because there is no upload. The speech engine runs inside your browser, the captions are drawn on your computer, and the finished video is saved straight to your Downloads folder. No account, no server, no copy of your work anywhere else.
