CapiCap: Video Captions

CapiCap adds subtitles to your videos — 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 Whisper (the same open speech model that powers professional tools), running entirely on your device's Neural Engine. There is no upload, no server, and no waiting in a queue — no network connection required at all.

HOW IT WORKS
1. Pick a video from your library or the Files app, or share one in from another app.
2. CapiCap transcribes it on-device, faster than real time on a recent iPhone or iPad.
3. Fix any words in the built-in editor.
4. Style your captions — start from twelve ready-made looks, then fine-tune fonts, weight, outline, colors, backgrounds, size and position, or pick Highlight to light up each word as it's spoken. 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.
- iPhone and iPad, one app. On iPad the editor gets room to breathe: a big preview with the whole caption list beside it.
- No watermarks, ever. Your exports are clean.
- Simple styling that looks good straight out of the box.

LIFETIME ACCESS
CapiCap is free to download, and your first 3 exports every month are on us. Want more? Lifetime access unlocks unlimited exports with one purchase — never a subscription.

REQUIREMENTS
Requires iOS 17 or later, on iPhone and iPad. CapiCap matches the speech model to your device: iPhone 13 and later, and iPad Air 5 and later, use Whisper Large v3, the most accurate model; older devices use the smaller Whisper Base. It downloads once on first launch. Works best on iPhone 14 Pro or newer and on iPad with an M-series chip, which transcribe faster than real time.
