Frequently asked questions
Is my video or audio uploaded?
No. Speech recognition and every edit run in your browser on your own device. Nothing is sent to a server.
Which files can I open?
SRT and WebVTT (.vtt). Styling tags are removed; text and timing are kept.
Do I need the video?
No, but adding it lets you see each line on the picture and jump to it.
What if a word is wrong?
Click the word and type the fix. Its timing stays the same, so word-by-word caption styles still line up. Find & replace fixes a name everywhere at once.
