Captn is a focused subtitle workflow for creators who need subtitles as the final deliverable, not just a small feature inside a big video editor. Upload a video or existing SRT/VTT file, generate subtitles, edit text and timing visually on the preview, translate captions, style subtitles, create clips, export SRT/VTT, burn subtitles into MP4, or export captioned green-screen videos for use in other editors.
