CaptionLab: AI Subtitles

About

CaptionLab turns raw video into clear, styled captions you can actually edit - without typing a single word by hand. Import a clip, pick your caption language, and AI creates timed subtitles. Every word stays yours to change. Fix a name, retime a line, restyle the look, move captions anywhere in the frame. Built for short-form creators, podcasters, educators, coaches, agencies, and anyone who needs videos to land with the sound off. WHAT YOU CAN DO - Generate timed captions from speech, automatically - Edit every word in a synced caption timeline - Translate captions into 40+ languages - Choose from 200 caption styles, then change type, colour, motion and position - Animate word by word, or keep it calm and readable - Place captions behind the speaker so the subject stays visible - Drag, pinch and reposition captions anywhere in frame - Export a captioned video with subtitles burned in - Export SRT and VTT subtitle files - Save projects and reopen them for editing - Add contextual B-roll, then replace or remove individual cutaways CAPTIONS THAT MATCH THE PLATFORM Each app covers a different slice of the screen. CaptionLab keeps your captions above the interface so they are never buried under a handle, a music ticker or a title bar. BUILT FOR MIXED-LANGUAGE VIDEO English, Roman Urdu, Hindi, Arabic, Spanish, French, German, Japanese, Korean, Chinese, Portuguese, Turkish, Persian and many more. Mixed-language speech is handled with context-aware AI, so names, slang and the terms that matter are easier to preserve.
