Is your website actually visible to ChatGPT, Claude, and Perplexity — or just to Google? GEO Scanner checks the signals that determine whether AI systems can find and cite your site: HTTPS, robots.txt access, https://schema.org markup, content freshness, JS dependency. You get a 0–100 score plus concrete fixes, not just numbers. Free, no signup, no API key. Web tool, KDE Plasma widget, GitHub Action, or MCP server 👉 https://www.agundur.de/geo-scanner.html #GEO #AIVisibility #SEO #OpenSource #KDE #GitHub
