How it works
Create AI captions in 4 steps
Captions Space transcribes the speech, times every word and exports ready-made captions for Reels, TikTok, Shorts and YouTube.
- 01
Upload a video
Drop a file into the window or pick it from your device — video, audio or an image.
- 02
AI transcribes speech
Speech becomes text with word-level timing, so a word lights up exactly when it is spoken.
- 03
Pick a style
58 ready-made styles and 111 font families — or build your own: color, outline, shadow, word animation.
- 04
Export the video
Take the finished video with burned-in captions, or a subtitle file: SRT, VTT, ASS.
Captions Space usually needs under 2 minutes for a short video, from upload to export
Templates
