Legible for Chrome

What it does

• Scans the site you're on when you press it: llms.txt, OpenAPI, MCP docs and the rest of our checks, the same scan as this site.
• Shows the score, how easy the site is to find, read and use, and the first three fixes, each with what it adds to the score.
• Opens the full result here for every check, the real file from whoever does each one best on our boards, and a fix prompt for your coding agent.

Chrome on a computer only, for now. It reads public files; it isn't a test of what an agent can do with a product.

Privacy

The extension, in Chrome

• When you press it, it sends one thing to our scan API: the domain of the tab you're on, like lyzr.ai. Not the page, not the full address, no cookies, no other tabs and no history. Like any web request, it also carries your IP address and your browser's name.
• It asks for one permission, activeTab, which lets it see that tab's address only when you press it. It never runs in the background or on a page by itself.
• The extension stores nothing in your browser and has no analytics or tracking of its own.
• It shows the site's icon from the address your tab already uses for it, usually from Chrome's cache.

Our scan API

• It reads that domain's public files. That's the scan.
• It keeps the result for up to 10 minutes, so a second look is free; anyone who scans that domain in that time sees the same public result.
• Our scan log keeps the last 20,000 scans: the domain, each check's result and when it ran. No IP address, no email and no browser details. We use it only to count how Legible is used and to improve its checks. We don't sell it, share it or use it to contact anyone.
• To keep the scanner fair, it counts live scans per network address for 10 minutes; the count then expires.
• It runs on Vercel, which hosts it and sees each request, IP address included, under Vercel's own terms, and on Upstash, the database for the cache, the log and those counts.

Our website, when you open the full result

• "Open the full result" opens this site, which isn't the extension. The site counts visits with Vercel Web Analytics and keeps its own counts of page views and button presses, with no ID for you.
• It loads each site's icon from DuckDuckGo, so DuckDuckGo sees which domains' icons it shows.
• Questions, or something we got wrong: rahulu626@gmail.com.

Rather not install anything? Drag the bookmark on home to your bookmarks bar: it does the one-press scan too, on our site.
