What tech is TikTok using to automatically generate alt text for images?

Answer: If you guessed artificial intelligence, you win.

With artificial intelligence taking the world by storm, it seems like everyone wants to use it in some form or another. TikTok’s latest move is to use it to improve accessibility.

The social media platform announced on Wednesday that it is testing a new feature that will use artificial intelligence to automatically generate alternative text for photos so that screen readers can read out a description of the image for visually impaired users. TikTok recently introduced the ability to add alt text for images, but it had to be done manually by the creator. With the new feature, AI will automatically add alt text to images if they don’t already have it.

The platform also announced two other new accessibility features: a new high-contrast mode to improve the user interface for users with low vision or sensitivity to low contrast, and the platform will follow a user’s bold text setting on their device for those who prefer or rely on bolder typeface.
