To add captions in CapCut, open your project, go to Text, then Auto Captions, choose the spoken language and tap Generate (on desktop the button may say Recognize or Create). The detail people skip: CapCut's help says background music and fast speech cause wrong words, so mute music first and check every line.
Plenty of people scroll with the sound off, on the bus, in a waiting room or late at night next to someone sleeping. If your video has no words on screen, they'll swipe past before you've said anything useful.
CapCut's Auto Captions listens to your voice and writes the subtitles for you, and it's one of the biggest time savers for anyone posting reels or tips videos for a small business. Here's how to run it on phone, desktop and browser, then fix the mistakes it makes, based on CapCut's own help pages.
Adding auto captions in the CapCut phone app
- Open your project and add your video.
- Tap Text in the bottom toolbar, then Auto Captions. Some versions also show Auto captions on the main screen.
- Choose the audio source and the spoken language, and pick a caption style if you're offered one.
- Tap Generate and wait while CapCut processes the speech.
- Play the video back with sound to check the words.
Menus vary by app version, so if you can't see Auto Captions under Text, update CapCut and look again.
Adding auto captions in CapCut on a computer
- Import your video and drag it onto the timeline.
- Open the Text tab at the top and choose Auto Captions.
- Pick the language and, if asked, the audio track to listen to.
- Click the button to start. CapCut's help calls it Recognize; another of its guides calls it Create.
- Your captions appear as blocks on their own track above the video.
Adding captions in CapCut online
In the browser editor, go to Text, then Auto Captions, choose the language and click Generate. CapCut's web start page also has an AI captions shortcut. Its guide says videos uploaded that way must be shorter than 20 minutes, and you'll edit lines in a Subtitles tab and pick a look in a Styles tab.
CapCut's help suggests Chrome or Edge, with clear audio, for the best results online. The browser version is handy when you're on a shared or work computer and can't install the desktop app, and the steps are close enough that you won't need to relearn anything.
| Version | Route to captions | Start button |
|---|---|---|
| Phone app | Text, then Auto Captions | Generate |
| Desktop | Text tab, then Auto Captions | Recognize or Create, by version |
| Online | Text, then Auto Captions | Generate |
Fixing wrong words in CapCut captions
Auto captions are speech recognition, and CapCut's help is upfront that they can mishear words because of background noise, accents, fast speech or poor audio. Always check them. Brand names and jargon are the usual casualties.
- Phone: select a caption clip on the timeline, tap Edit captions and tap a line to retype it.
- Desktop: double-click a caption block, or right-click and choose Edit Captions. Changes save automatically.
- Online: click a caption block, then Edit captions in the right panel.
Long lines are harder to read and harder to fix. Split them at natural pauses. On desktop that's Ctrl and B on Windows or Cmd and B on a Mac. On the phone, place the playhead and tap the scissors, or long-press and choose Split.
Getting more accurate CapCut captions first time
CapCut's advice boils down to giving the speech recognition a clean voice to hear:
- Remove or mute background music and effects before you generate. You can add the soundtrack back afterwards, and my guide on adding music in CapCut covers which tracks you can use.
- Speak slowly and clearly, especially around technical terms.
- Avoid two people talking over each other.
- Record in a quiet room with a decent microphone.
If a whole section comes out garbled, CapCut says re-running captions on just part of a clip isn't built in. The workaround is to delete the bad block, mute the other audio and add auto captions again so it only hears your voice.
Styling captions in CapCut so they're readable
Edit soon after generating, while you still remember exactly what you said. CapCut's help recommends it, and it's far quicker than rewatching a clip a week later. Then preview the whole video with sound before you export.

Once the words are right, make them easy to read. On desktop, CapCut's help suggests using the Style tab so every line matches, and the Text, Animation and Tracking options to change font, size and layout. On mobile you can change fonts, styles, effects and animations from the caption editing tools.
Some habits that work well for business content:
- Use your brand font only if it stays readable at phone size.
- Keep captions away from the very bottom, where app buttons and descriptions sit.
- Highlight one key word per line in your brand colour.
- Keep to two short lines at most.
On-screen captions versus the caption you post
Different things share the name. CapCut captions are subtitles burned into the video. The caption you type when posting is the text under the video. Both matter. If you want help with the written kind, see my tips on writing Instagram captions that get people engaging.
If CapCut auto captions won't work
- No words at all? Check the clip has audible speech and the right audio track is selected.
- Wrong language? Delete the captions and generate again with the correct language chosen.
- Words badly wrong? Mute music and effects, then re-run Auto Captions.
- Can't find Auto Captions? Menus vary by app version; update CapCut and check the Text menu.
- Online upload refused? CapCut's AI captions tool wants videos shorter than 20 minutes.
