App Description
Private on-device captions, 50 styles, live animation, and MP4 export.
Create polished, accessible videos with Offline AI Auto Captions. Turn speech into timed captions, edit every line, style the words, and export a finished video from your phone.
PRIVATE ON-DEVICE WORKFLOW
After an optional one-time model download, speech recognition and caption editing run on your device. Your video and audio are not uploaded to a transcription server. Choose a lightweight model for lower-memory phones or download a stronger model when your device has the storage and memory available.
CAPTION STUDIO
- Import a video from Photos or Files, or start with the editable sample project.
- Generate captions with automatic language detection or choose a language explicitly.
- Edit text, split and merge lines, retime IN and OUT points, and undo or redo changes.
- Drag captions in the preview, pinch or corner-drag to resize, and adjust safe width and placement.
STYLE EVERY WORD
- Apply 50 caption style recipes with one tap.
- Choose fonts, sentence case, uppercase, colors, bold text, outlines, shadows, and background boxes.
- Add 38 live text animations including word highlight, karaoke, typewriter, glow, pulse, and motion effects.
- Use 14 separate entrance and exit transitions.
- Add speech hints for names, brands, and technical terms.
LANGUAGES AND ACCURACY
Select from 50 languages or let the app detect the spoken language. Whisper models use voice-activity detection, overlapping context windows, beam search, word timestamps, and visible progress so you can follow generation on your device.
EXPORT YOUR WAY
- Render a real burned-in MP4 with styled captions at Original, 1080p, or 720p.
- Save exports to Movies/OfflineAutoCaptions and share them from Android.
- Export SRT and WebVTT subtitle files, TXT transcripts, or styled ASS files for desktop editing.
GO PRO
Pro unlocks unlimited daily projects, background-safe batch processing for up to 10 videos, larger high-accuracy models, and advanced MP4 rendering and styled ASS export. The free version includes up to three captioning projects per day.
Make your captions readable, expressive, and ready for TikTok, Instagram Reels, YouTube Shorts, and more — with the editing tools on your phone and your speech kept private.
