Auto captions that keep up

Aybuke's video editor writes captions for you from what's said in your video. Apple's speech recognition runs on your iPhone, iPad or Mac, so the sound and the words never leave it, and captions never use credits.

How to add captions to a video

1. Open the video editor

   Tap Video on Explore, or Edit a video in the Edit tab, and choose a clip. Videos can be up to 5 minutes; for a longer one, Aybuke uses the first 5:00.

2. Tap Add captions

   Under Auto-cut silences, tap Add captions. Aybuke listens to your video and writes the captions. The first time, a language may need a one-time download.

3. Pick a style

   Tap Edit, then choose Pop, Bubble, Candy, Karaoke or Typewriter, and set the position and size.

4. Fix any word

   Correct a caption's text, change when it starts and ends, or delete it. Add a caption of your own at any point in the video.

5. Cut, trim and save

   Turn on Auto-cut silences, trim the ends and add an effect if you like. The captions move with every cut. Then save to Photos or share.

Five caption styles

Captions sit at the bottom or in the middle, in small, medium or large. Each one shows up to two balanced lines and changes at natural pauses, so it's easy to read on a phone. If you rewrite a caption, Karaoke shows that one like Pop.

In sync after every cut

Captions are made once, from the whole clip. When you trim the start or end or turn on Auto-cut silences, Aybuke moves each caption with the moment it belongs to and drops the ones from parts you cut, so you never have to make them again. In the caption list, those are marked “Cut from the video”.

Captions are drawn on top of an effect's date stamp, camcorder display or letterbox, and the preview matches the video you save.

Which languages work?

Automatic captions work in the languages your device can recognize without the internet. Aybuke starts with the app's language, or your device's, and you can pick another under Language.

• iOS 26, iPadOS 26 and macOS 26 or later: each language's speech model downloads once from Apple. No audio is sent with that download.
• Earlier versions: your device asks for permission to use speech recognition first, and only languages it can recognize offline are offered.
• No match, or no words? Type your own captions at any moment of the video.

Copy captions as a subtitle file

Need your captions somewhere else? Copy captions (SRT) copies them as SubRip text, timed to your edited video, for apps and sites that import .srt subtitle files.

More in the free video editor

Captions are one part of Aybuke's video editor. Auto-cut silences removes the pauses between sentences for a jump-cut rhythm, ten retro effects plus Tiny World give your clip a look (Camcorder '06 even shows a running timecode), and you save with no watermark and no ending clip. Our jump-cut guide has tips for recording talking videos that cut cleanly.

Private by default

Captions are made on your device with Apple's speech recognition. The sound and words of your video are never uploaded to us or to Apple, and captions are kept only while you edit and in the videos you save or share. Read more on our safety page.
