AI Checker by Signum.AI - Check if AI agents can see your website for free

Most websites are built for Google, not for AI agents. Many accidentally block GPTBot or ClaudeBot, have no llms.txt, or hide content AI can't read. AI Checker scans your domain and gives you an AI Readiness Score in seconds, covering AI bot access (robots.txt), llms.txt, content structure and performance. Plus clear tips on what to fix so ChatGPT, Claude and Perplexity can find and cite your site. Free, no signup.

Hey Product Hunt! 👋 I'm Artem, founder of Signum.AI. I've spent 18 years in marketing and SEO, and over the last year I kept seeing the same thing with clients: great sites that rank on Google but are almost invisible to ChatGPT, Claude and Perplexity. The reasons are usually boring and easy to fix: AI bots blocked in robots.txt, no llms.txt, content AI agents can't read. Most site owners just don't know. So we built a free AI Checker: - Enter your domain, get an AI Readiness Score in seconds - See exactly what's blocking AI agents - Get clear tips on what to fix No signup, completely free. Since we quietly released it, people have run 4,000+ checks on 1,500+ domains. Would love your feedback: what else should it check? And drop your score in the comments, curious to see who's AI-ready 🙂
