## Key facts

- What it does: automatically transcribes the English speech in a video, shows it as single-word captions timed to the speech (each word pops in subtly), lets you edit, delete and reorder words, style the captions, and export a new movie with the captions burned into the picture.
- Platforms: iPhone and iPad, iOS/iPadOS 17.0 or later, A12-class chip or newer (for example iPhone XS, iPhone XR, iPhone SE 2nd generation or later).
- Pricing: free download. Free plan covers videos up to 2 minutes, with all caption styles and export and no required watermark. CaptionAddr Pro is an auto-renewing subscription through Apple, billed monthly or annually (US$6.99 per month or US$39.99 per year in the US; the App Store shows local prices), for videos up to 30 minutes. Eligible new subscribers get a free trial: 7 days on the annual plan, 3 days on the monthly plan.
- Privacy: transcription runs on the device with a bundled English speech model (NVIDIA Parakeet TDT 0.6B v2); CaptionAddr does not send your video, audio or captions to its servers for transcription. No account is required. The app uses online services for purchases, diagnostics, security and aggregate usage counts.
- Language: English speech only. No translation and no other transcription languages.
- Styling: 20 caption fonts, adjustable size and an optional tinted background; drag captions into position. Captions are always white uppercase text with a dark outline; there are no color, weight, outline or letter-case controls. A small CaptionAddr watermark is optional and off by default.
- Export: a re-encoded movie with burned-in (open) captions, saved to Photos and shareable to any app, including Instagram Reels, TikTok, YouTube Shorts, Facebook Reels, Snapchat Spotlight and LinkedIn.
- Export format: a QuickTime movie (.mov) in the video’s own shape, up to 4K and up to 60 frames per second; H.264 video, or HEVC for 4K above 30 frames per second; videos smaller than 1080p are scaled up to 1080p; HDR and Dolby Vision video is converted to standard dynamic range.
- An export in progress can be canceled without losing caption edits.
- Not supported: SRT/VTT or text transcript export, manual per-word timing, full-sentence caption layouts, batch processing, posting directly to social platforms.
- Differentiators: on-device transcription (no upload), no required watermark, no account, word-by-word captions designed for short-form video, simple one-video workflow.
