BotLens

Analyze if a website is readable by AI (LLMs, crawlers, and bots).

Can AI read your website? BotLens is a one-click Chrome extension that tells you exactly how AI crawlers and language models see any page you visit — from GPTBot and ClaudeBot to Perplexity, Google-Extended, and a dozen others. Click the icon on any site and BotLens instantly runs a technical audit: 🤖 robots.txt & Meta Analysis Parses the site's robots.txt with proper Allow/Disallow precedence and wildcard support. Detects blocks against 20+ known AI user-agents, plus meta directives like noindex, noai, and noimageai. 🌳 Semantic Structure Checks heading hierarchy, HTML5 landmarks, structured data (JSON-LD), image alt-text coverage, and the lang attribute — the signals LLMs rely on to understand content. ⚡ JS Rendering Detection Compares the initial HTML payload to the rendered DOM to catch SPA shells that hide content from bots. Shows you when a site depends on JS to render text that crawlers cannot see. 📊 A weighted 0–100 score Every signal contributes to a single readability score you can act on — plus a plain-language verdict so you know whether to celebrate or start fixing. 🔒 Privacy-first Everything runs locally in your browser. No accounts, no analytics, no data collection.
