Free on App StoreAnimated Subtitles.
Zero Effort.
Total Privacy.
Add word-by-word animated captions to any video, directly on your iPhone. No account. No upload. No subscription — ever.
Face Tracking
Captions that follow the speaker.
SnapScript detects faces and tracks who's speaking in real time. Captions automatically reposition above the active speaker — a feature found only in professional broadcast software, now on your iPhone. Works in the exported video, not just the preview.
The Difference
Same video. Completely different impact.
Without captions, your audience scrolls past. With SnapScript, every word lands: animated, styled, impossible to ignore.
Most caption apps charge €10–25/month and upload your footage to their servers.
SnapScript runs entirely on your device. No server, no account, no recurring bill.
Caption Animations
Every word moves.
Forget static blocks of text. SnapScript animates each word individually — 9 animation styles, each with precise timing curves. Your captions feel alive, not pasted on.
Privacy by Architecture
We can't see your videos. We don't have a server.
All transcription runs on-device using Apple's Speech framework and Whisper. There is no account, no upload, no analytics SDK, no ad network. The app is silent on the network because there is nothing to send.
