Easily see alt text on Bluesky. Get tips on accessible text. Get warned or prevented from posting inaccessible posts.

It can be difficult to tell if images have alternative text on Bluesky. Alternative (or alt) text is used to describe images for those who can't see the image, making them more accessible. This extension, based on Alt or Not for Twitter, shows which images are missing alternative text, and displays the alt text below the images when available. The extension also warns users when images in a post have no alt text when posting, and you can choose to disable the button entirely when alt text is missing, requiring you to add descriptions before you can post. You can choose to hide the repost button on posts with missing alt text, or even hide the complete post. The extension includes additional options to check the text of posts for potential accessibility issues, giving suggestion on how to avoid those issues.
