Image Description Generator is a browser extension for Chrome that handles the tedious parts of working with images on the web. Install it, click the toolbar icon, and you can upload or paste a picture — or simply right-click any image you find while browsing — to get an AI-written description of it. From the same menu you can produce SEO-oriented alt text, a short social-media caption, or pull the words out of the image as extractable text.
The extension is aimed at people who constantly touch images in their workflow: content creators filling in blog alt attributes, developers and designers keeping sites accessible, marketers writing captions and campaign copy, social media managers, and educators or researchers who need the text inside a chart or slide. Two of its strongest angles are accessibility — descriptions that work with screen readers — and SEO, since well-written alt text is both a ranking and a compliance signal.
With roughly 900+ users, a 3.8-star rating and version 1.0.0 last updated in December 2024, it is a lightweight, single-purpose utility rather than a full image platform. The developer states that the extension does not collect or sell user data. Expect a simple tool: quick results on any page, in dozens of interface languages, with no advanced editing suite attached.
Generate keyword-relevant alt descriptions for blog and page images without writing each one by hand.
Produce descriptions suitable for screen readers so image content is available to assistive technology.
Get instant caption ideas for social posts from photos you are already looking at.
Turn text inside slides, diagrams or scanned material into copyable text for notes and papers.
