AIScan — AI Readiness Checker

Scan any site for AI-agent readiness. Get an instant score, grade, and the top fixes — without leaving the page.

Is your favourite website ready for the AI agents that are about to visit it? AIScan is a one-click scanner that grades any website on how well it supports AI agents, LLMs, scrapers, and automated tools. Click the extension icon on any page and get an instant score, a letter grade, an AI-readiness level, and the top issues to fix — without leaving the tab. It's free, no signup required, and works on Chrome, Edge, Brave, Arc, and any Chromium browser. What it does - Runs a full AI-readiness scan on the active tab's URL - Returns a score out of 100, a letter grade (A+ to F), and an AI-readiness level - Lists the most impactful failing checks so you know exactly what to fix - Links to the full report on aiscan.site with every check explained - Works on any public webpage — landing pages, docs, dashboards, blogs, ecommerce sites The 5 AI-readiness levels 1. Hostile — actively blocks agents 2. Indifferent — agents can reach it but the experience is poor 3. Discoverable — basic SEO and metadata are present 4. Interactive — structured data, clean semantic HTML, predictable endpoints 5. Agent-Native — robots.txt AI directives, llms.txt, JSON-LD, clean APIs What it checks - Crawlability — robots.txt, AI-bot directives, sitemap.xml, canonical URLs - Discoverability — title, meta description, Open Graph, Twitter cards, favicon - Structured data — JSON-LD schema, microdata, Article/Product/Organization - AI-native signals — llms.txt, llms-full.txt, /.well-known/ai-plugin.json, MCP - Performance — HTML response time, content-type, valid HTTPS - Agent ergonomics — semantic HTML, ARIA landmarks, text-to-markup ratio - Anti-agent friction — aggressive bot-blocking, JS-only rendering, dark patterns How to use it 1.
