SubCaptionsA subtitle editor that works on top of the video
Most subtitle editors make you scrub a waveform in a separate window from the video. This one puts the captions on the video. Load any YouTube link, build your captions in time with what's on screen, edit any line, and export. Nothing to install.

Frequently asked questions
What makes this different from desktop subtitle editors?
It runs in the browser with the video front and center, so you caption in context and see each line on screen as you save it. No install, no project files, and it remembers your work locally.
Can I edit subtitles I already made here?
Yes. Reopen the same video and your captions are still there to edit. To translate or convert an existing file, use the file translator.
What formats can I export?
Standard .srt and .vtt, which import into YouTube, Premiere, DaVinci Resolve, Final Cut, and CapCut.
