Paste a URL, upload a screenshot, or run axe-core in your browser, find out what's broken, who it affects, and exactly how to fix it.

Website URL

Works best on static and server-rendered sites. React SPAs may give limited results.

Go to the website you want to test in Chrome
Open DevTools (F12 or Cmd+Option+I) and go to the Console tab
Paste and run this command:
Console
var s=document.createElement('script');s.src='https://cdnjs.cloudflare.com/ajax/libs/axe-core/4.9.1/axe.min.js';s.onload=()=>axe.run().then(r=>console.log(JSON.stringify(r)));document.head.appendChild(s);
Paste the JSON output in the field below

Or install the free axe DevTools Chrome extension for a one-click experience.

About

AccessCheck AI analyzes websites using three methods: paste a URL for automatic HTML analysis, upload a screenshot for visual inspection, or run axe-core in your browser for confirmed results. Every issue comes with a plain-language explanation of who is affected, and a before/after code example showing exactly what to change.

Designers
Spot contrast, layout, and visual issues before handing off to developers.
Developers
Get specific before/after code fixes for every accessibility problem found.
Product teams
Understand your product's accessibility health without needing to be an expert.

Choose your analysis method
Pick from three options: paste a URL for automatic analysis, upload a screenshot for a visual check, or use axe-core in your browser for the most accurate results. Each method is suited to different situations.
The page is scanned for issues
For URLs, the HTML is fetched and analyzed by Gemini AI. For screenshots, the image is checked visually for contrast, layout, and labeling problems. For axe-core, real browser tests are run against your live page and only confirmed violations are reported.
Issues are sorted by how certain they are
Each finding is labeled Confirmed (proven from the code), Likely (probable but depends on context), or Improvement (a usability suggestion). This way you always know how much to trust each result.
See exactly what to fix and how
Every issue includes a plain-language explanation of who is affected and why it matters, plus a before/after code example showing the problem and the fix side by side.
