Free Online AI Image Alt Text Writer

1. Describe what the image shows in the input box.
2. No options needed—the tool returns concise alt text.

An AI alt text generator writes the short description that screen readers announce and search engines index for an image. It conveys the meaningful content and context concisely—ideally under 125 characters—without redundant prefixes like 'image of,' which screen readers add automatically.

Web developers, content teams, and bloggers use it to make images accessible and to improve image SEO. You describe what the image shows, and the tool returns a single, ready-to-paste line of alt text.

Your description is sent to a secure AI API to generate the alt text and is not stored afterward. Review it to confirm it accurately reflects the image and its purpose on the page before adding it to your markup.
