Captn

Captn is a browser-based subtitle editor for creators, freelancers, course makers, and video teams who need cleaner captions without using a heavy video editor.

Upload a video, generate subtitles automatically, or import an SRT/VTT file. Then fix text, timing, line breaks, styling, and translations directly on the video preview. When the captions are ready, export SRT, VTT, captioned MP4s, clips, green-screen captions, or translated subtitle versions.

Captn is built for people who want more control than basic auto-caption tools, but do not want to fight a full editing timeline just to clean up subtitles.
