Captn - A focused subtitle editor for creators and video teams

We built Captn because most subtitle tools are good at generating captions, but frustrating when you actually need to fix them. The problem we kept seeing was simple: auto-captions are rarely ready as-is. People still need to correct transcript text, timing, speaker changes, styling, and exports, and that usually means jumping between multiple tools or fighting a clunky editor. Captn is our attempt to make that workflow much cleaner. You can upload a video, generate subtitles, edit the transcript and subtitle blocks in one place, adjust timing, work with speaker-aware transcript flows, preview everything directly in the browser, and export a captioned video without leaving the app. We focused less on “one-click captions” and more on what happens after transcription, the part where real editing work begins. Would love to hear what feels most broken in your current subtitle workflow, and what tools you’re using today.
