Alt or not is a browser extension / add-on for Chrome, Firefox, and Edge. Easily see which images include alt text or not on Twitter (also supports GIF) and TweetDeck, and get a warning when posting images without alt text.

It's often difficult or cumbersome to tell if images have alternative text on Twitter or TweetDeck. Alternative (or alt) text is used to describe images for those who can't see the image, making them more accessible.

This extension 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 tweet have no alt text when tweeting, and you can choose to disable the button entirely when alt text is missing, requiring you to add descriptions before you can tweet.

Version 1.1 introduces an option to hide tweets from accounts using an NFT profile pic.

Note: on TweetDeck descriptions are not displayed on GIFs.
