From now on, all videos attached to tweets will have auto-captions enabled. Captions will be activated for in-stream videos that are muted, on both iOS and Android, while desktop users will be able to switch them on and off as they choose.
Twitter's auto-captions are available in 37 languages, and while translation is not available as yet, the captions will appear in the language of the device used to upload the clip. Also, a key downside, Twitter's auto captions are not editable at this stage. Both translation and editing tools are still in development.
The announcement is the latest advance in Twitter's accessibility features, which got a boost last year with the announcement of two new internal teams focused on ensuring optimal utility for all users. That came after the company was criticized for launching audio tweets without a captions option, which helped Twitter recognize the need for more dedicated focus on his front.
Twitter also announced auto-captions for voice tweets last year (which it began testing in July), while auto-captions are also available for Spaces. But auto captions in regular videos may be the biggest step yet. And as noted by TechCrunch, it could also be particularly valuable in Twitter's revamped Explore tab, which is currently in testing, and presents tweets in a more TikTok-like full-screen, vertical scrolling format.
