AI Content Visibility Checker, powered by VisibilityStack

Score any page for AI search. See how LLMs (ChatGPT, Gemini, AI Overviews) read it — with fixes to get cited.

See any web page the way AI crawlers and large language models actually read it — and fix what's holding you back from being cited in AI search. As search shifts to ChatGPT, Gemini, Perplexity, and Google AI Overviews (GEO — generative engine optimization), getting cited depends on whether AI can cleanly parse your page. This free tool, powered by VisibilityStack, gives you an instant AI-Readability score and a prioritized fix list for any page — no signup. Click the toolbar icon and get, in a side panel: • AI-Readability Score — a 0–100 grade of how well AI engines can read and cite the page. • Server-side rendering (SSR) check — the #1 GEO issue: we compare the raw HTML a non-JS crawler sees against the rendered page, so you know if your content is invisible to AI. • Fix list — specific, prioritized recommendations (structured data, headings, meta, thin content, alt text, and more). • AI Preview — the clean text an LLM ingests, stripped of nav and clutter. • Details — heading hierarchy with rendered font sizes and visual-hierarchy flags, links, images with alt-text coverage, and JSON-LD structured data. • Shareable report card — a branded image of the page's score. Built for SEO and GEO teams, marketers, and founders who want to win AI search visibility. Privacy: the extension only reads a page when you click it, processes everything on your device, and sends nothing to any server. No account, no tracking.
