Bluesky Alt Text Generator — symmetricalboy

This browser extension helps you generate detailed, accessible alt text for images and videos you add to posts on Bluesky, using Google Gemini AI.

Once installed, the extension is active on bsky.app.
When you upload an image or video and open the alt text input field (usually by clicking "ALT" or a similar button on the media preview), you will see a ✨ icon appear next to the text area.
Click this icon to generate alt text based on the media.
Review: Always review the generated alt text before posting! AI can make mistakes. The generated text will appear in the input field, and a toast notification will confirm success or report errors.
