ImgSEO

ImgSEO is a browser-based alt text generator built for the people who maintain websites: developers, content editors, SEO specialists and e-commerce managers. Once installed in Chrome, it opens as a side panel and lets you generate alternative text for images either one at a time through a right-click context menu or in bulk across a page, a folder or an entire media library. The AI looks at the image itself plus optional surrounding signals such as the file name, page title and meta description, so the output reads like a human description of what the picture actually shows rather than a keyword dump.

What separates ImgSEO from a simple caption generator is its schema system. Because content management systems store media in predictable structures, you can describe that structure once — for example the CSS selector or DOM path where a product image lives — and ImgSEO will reuse the same recipe on every page that matches it. That makes it practical to run a large catalogue through the tool without hand-configuring each image. Generation options include target language, maximum character length and whether context fields should influence the result.

Pricing follows a freemium credit model: installing the extension and signing up gives you a starter credit balance to try generation, and heavier usage is handled through in-app purchases. A companion WordPress plugin extends the same AI alt text workflow into the WordPress dashboard for media libraries. The extension is published by an independent developer, not by Google, and its privacy disclosure states that it handles authentication details, website content and personally identifiable information for the service to function.
