# Kwotable > The PageSpeed Insights of GEO (Generative Engine Optimization). Paste a URL and get a 0–100 score for how readable and citable your site is to AI answer engines — ChatGPT, Claude, Perplexity and Gemini — plus weekly AI visibility tracking that alerts you when a competitor takes your spot. Kwotable has two layers: a free, deterministic GEO analyzer (no signup, 10 scans/day) that scores crawler access, content structure, structured data, authority/freshness and technical setup; and a paid visibility-tracking layer that runs your buyer's real questions against AI chat engines on a schedule and reports whether your brand gets cited. ## Docs - [Homepage](https://kwotable.io/): product overview, live scoring demo, how it works, pricing. - [Pricing](https://kwotable.io/pricing): full plan comparison — Free, Indie, Starter, Pro. - [Blog](https://kwotable.io/blog): GEO explainers, AI-engine citation behavior, and data from real scans. ## Blog posts - [We analyzed 500 indie sites.
