Free AI Visibility Checker
See whether ChatGPT, Claude, Perplexity, and Gemini can find, understand, and cite your brand.
One free scan checks bot access, structured data, llms.txt, and content signals, then returns a single 0-100 AI visibility score with a prioritized fix list. It runs on our AI Readiness Score engine.
What the checker measures
Can OpenAI, Claude, and Perplexity retrieval agents and search engines reach your pages? Checks robots.txt, meta robots, and header rules across 17 crawlers, with training policies assessed separately.
JSON-LD coverage and quality: Organization, Article, and the other schema types that declare your brand and pages.
llms.txt presence, structure, entity definitions, and use policy. It counts toward this score but is optional: Google says Google Search ignores it.
Server-side rendering, title and description quality, and whether your content is readable without JavaScript execution.
How well your signals agree: structured data, llms.txt, bot access, and SSR working together instead of contradicting each other.
Why AI visibility matters
AI search engines increasingly answer questions that used to start on Google. When someone asks ChatGPT, Claude, Perplexity, or Gemini about your category, those engines pull from sources they can crawl, parse, and trust — and they name a short list of brands in the answer. If they cannot access or understand your site, you are invisible at the exact moment a buyer is deciding.
Traditional SEO checks how you rank. An AI visibility checker checks something different: whether AI systems can find your content, recognize your brand as an entity, and cite you in their answers. This free checker measures the technical signals that determine that outcome.
How the score works
The checker runs our AI Readiness Score engine, which synthesizes five weighted categories into one 0-100 score and an A-F grade. Run the full tool for the complete category breakdown.

Frequently asked questions
What is a free AI visibility checker?
A free AI visibility checker tests whether AI crawlers can reach and read your website. It inspects bot access, structured data, llms.txt, and content accessibility, then returns a single technical readiness score. It does not ask AI models about your brand, so it shows whether your site is technically readable, not whether ChatGPT, Claude, Perplexity, or Gemini currently mention or cite you. Pixelmojo runs this check for free using the AI Readiness Score engine.
Is this AI visibility tool actually free?
Yes. The AI visibility tool is free with a one-time email verification (a 6-digit code). You get one audit per email with a 0-100 score, an A-F grade, and a prioritized action roadmap. No credit card and no trial are required. Paid tools like the AEO Page Auditor and AI Citation Tracker are clearly marked and separate.
What does an AI search visibility checker measure?
An AI search visibility checker measures five things: bot discoverability (can AI crawlers reach your pages), structured data quality (your JSON-LD schema), llms.txt (an optional summary file for AI tools), content accessibility (server-side rendering and readable content), and cross-signal readiness (whether all of those signals agree). Each feeds a weighted 0-100 score.
What is an LLM visibility checker and how is it different from an SEO tool?
An LLM visibility checker looks at your site the way AI systems access it, rather than how you rank in the ten blue links. This free check covers technical readiness: whether AI crawlers can reach your pages and read your content. Whether AI models actually mention or cite your brand is measured separately by Radar’s paid AI-response tools, which query the provider APIs. Traditional SEO and AI readiness overlap but are not the same.
