CapiCap: Video Captions

CapiCap adds subtitles to your videos in 99+ languages — automatically, and 100% on your device.

No watermarks. No ads. No subscriptions. No account. No tracking. Nothing you make ever leaves your device.

Pick a video and CapiCap transcribes it locally using a state-of-the-art on-device speech model. No upload, no server, no waiting in a queue, and once the model has downloaded it works offline.

HOW IT WORKS
1. Pick a video from your library or the Files app, share one in from another app, or on iPad, iPhone Duo and Mac drop it anywhere on Home.
2. CapiCap transcribes it on-device, faster than real time on a recent iPhone, iPad or Mac. If it isn't sure which language is spoken, it asks instead of guessing.
3. Fix any words in the built-in editor. While you type, a bar above the keyboard plays the video and hops between captions.
4. Style your captions — start from twelve ready-made looks, then fine-tune fonts, weight, outline, colors, shadows, backgrounds, animation, size and position. Light up each word as it's spoken, show one word at a time, or set the caption behind the person on screen. Save your favorites as your own looks.
5. Export a new video with the captions burned in, ready to share.

Prefer a subtitle file? CapiCap also exports a standard .srt you can use anywhere.

WHY CAPICAP
- Private by design. Transcription happens entirely on your device — your videos and words are never uploaded.
- Works offline. No signal, no problem. Everything runs locally.
- Understands 99+ languages. CapiCap recognizes the language of your video automatically, or you can pick it yourself.
- iPhone, iPad and Mac, one app. On iPad, Mac and an open iPhone Duo the editor gets room to breathe: a big preview with the whole caption list beside it.
- No watermarks, ever. Your exports are clean.
- Original quality. Exports keep your video's resolution, frame rate and bitrate, 4K60 included. Nothing is downscaled, and the sound is copied as is.
- Simple styling that looks good straight out of the box.

LIFETIME ACCESS

REQUIREMENTS
Requires iOS 17 or later on iPhone and iPad, or macOS 14 or later on a Mac with Apple silicon (M1 or later). The speech model downloads on first launch, and another only if a video's language needs it. Works best on iPhone 14 Pro or newer, on iPad with an M-series chip and on the Mac, which transcribe faster than real time.
