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.
Overlays alt text labels on all visible <img> elements with color-coded status (green=exists, yellow=empty/short, red=missing)Checks SVG elements for <title> and <descr> accessibility metadataDetects missing alt attributes, empty alt attributes, and short alt text (<10 chars)Processes child iframes recursively up to 25 levels deepToggle on/off via extension icon click with active/inactive icon states

- 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

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.
Works as expected. Displays alt tags on each image or "Empty alt attribute" if it is missing. Great when your alt tags are deep in the code.
Does not allow selection, copying of alt text.
Works as expected. Thank you for building this.
Great work, thaks for your effort. Works perfectly.
Tuyệt vời..! Kiểm tra website rất tiện lợi.
Does what it says on the box!
Works well. Could be nice to remove "Short alt text: " though showing only the actual alt text without this line
It seems to want a <descr> tag on svg files, but I believe the correct tag is <desc>
good tool
I'd love if this was more than just an alt extension. I'd love if it exposed aria-labels and other screen-reader features to show the true screen reader experience or even if different labels/tags/attributes were selectable.
