Capster: AI Captions for Video

Capster turns the speech in your videos into animated, word-by-word captions. Import a clip, tap generate, and every word is transcribed, timed, and ready to style and burn into your video.

Most people scroll with the sound off. Captions keep them watching, and Capster saves you from timing them by hand.

AUTO CAPTIONS IN 99 LANGUAGES
- Import videos from Photos or Files
- Speech is transcribed automatically, with timing for every word
- The spoken language is detected automatically, across 99 languages
- Translate captions into 86 languages, including Spanish, French, German, Portuguese, Hindi and Japanese
- Long lines split into short, readable captions automatically
- No speech in the clip? Add captions yourself

ANIMATED CAPTION STYLES
- 17 ready-made presets: Plain, Yellow Desert, Comics, Pink Sun, Midnight, Glow and One Word
- 6 cinematic real estate shorts type styles
- Every preset plays a live animated preview
- 18 caption fonts, with size, color, letter case and alignment
- Outline, drop shadow, and a background with color, corner radius and padding
- Karaoke-style highlighting gives the spoken word its own color and background
- Word pop, plus fade, slide, scale and pop in and out animations
- Top, center or bottom placement, or place captions exactly where you want
- Save your own styles and reuse them on other videos
Some styles and controls require Capster Pro.

EDIT WORDS AND TIMING
- Tap any caption to fix its text
- Retime a caption by setting its start or end to the playhead

- Save to Photos in one tap as a high-quality MP4
