AI 产品解读Displays alternative text (alt text) overlays on all images and SVGs on a web page for accessibility auditing
Helps web developers and accessibility auditors quickly identify images with missing, empty, or short alt attributes — a common accessibility compliance issue that affects screen reader users
User clicks the extension icon on any web page → the extension injects alt.js into the active tab → alt.js scans all <img> and <svg> elements in the page and its iframes → color-coded overlay labels are displayed on top of each image showing the alt text status. Clicking the icon again toggles the overlay off.

- Extension is very small (4 text files, 39 lines in service-worker.js, 171 lines in alt.js) making full analysis straightforward with high confidence
付费分析未识别到付费功能
No billing, subscription, license, upgrade UI, or payment platform integration exists anywhere in the source. The 'pro' keyword matches were false positives: one from the word 'process' in a comment (alt.js:161) and one from the verified_contents.json metadata. The extension is entirely free with all features available on install.

- The extension has no login UI, no authentication flow, and no calls to any external service requiring an account. It operates entirely client-side by injecting a script into the active tab. The only keyword match for 'auth' was the 'author' field in manifest.json — a false positive.
