A free auto captions app for iPhone and iPad
Updated
CaptionAddr is a free auto captions app for iPhone and iPad: it listens to the English speech in your video, writes word-by-word captions automatically on the device, and exports a captioned copy. The free plan covers videos up to 2 minutes with every caption style and no required watermark.
What “auto captions” means in CaptionAddr
You choose a video, and CaptionAddr turns its spoken English into captions without you typing anything. Each caption is a single word timed to the speech, the punchy style common in short-form video. You then review the words, fix anything the model misheard, choose a look, and export a new movie with the captions built into the picture.
The transcription model ships inside the app. That means the speech recognition happens on your iPhone or iPad rather than on a server, and there is no account to create before you start.
What you get for free
- Automatic English transcription on your device
- Word-by-word captions you can edit, delete and reorder
- All 20 caption fonts, with size and tinted-background controls
- Export of a captioned movie saved to Photos
- No required watermark (a small CaptionAddr watermark is optional)
The free plan works with videos up to 2 minutes long. CaptionAddr Pro is an optional monthly or annual subscription through Apple that raises the limit to 30 minutes per video. The App Store shows the current price in your currency before you buy.
How to auto-caption a video
- Choose a clip. Tap Select Video and pick one video from Photos.
- Let the captions generate. Captions start as soon as the video opens; keep CaptionAddr open while it transcribes.
- Review the words. Play through the clip in Edit Captions and correct, delete or reorder words.
- Pick a style. Choose a font, adjust the size and drag the captions into position.
- Export. Save the captioned movie to Photos, then share it wherever you post.
Honest limits
- English only. The model is designed for English speech. Other languages and translation aren’t supported.
- Burned-in captions only. There is no SRT or VTT file export; captions are part of the exported video.
- Automatic timing. Timing follows the speech and can’t be set per word by hand.
- Not perfect. Music, noise, overlapping voices and strong accents can cause mistakes, so review before you post.
- One video at a time. CaptionAddr works on one current project; there’s no batch captioning.
