AutoCaptioner
AI video subtitles in the browser — transcribe, edit and style captions, then export burned-in video or SRT/VTT
About
AutoCaptioner is a browser-based AI video subtitle generator and caption editor: upload a video, AI transcribes audio in 20+ languages, edit text and timing, style captions with 25+ presets or custom styles, and export video with burned-in subtitles or SRT/VTT/TXT. Video itself stays on device and is processed locally in the browser; only extracted audio is sent to the transcription provider.
- Upload a video and let AI transcribe it, then edit text and timing in the editor.
- Pick a caption preset or build a custom style.
- Export with burned-in subtitles, or as SRT/VTT/TXT for use elsewhere.
