What it checks
17 checks in four groups
The extension looks for the technical and content issues that make a page harder for AI assistants and search engines to access or interpret. Rules come from OpenAI, Anthropic, Perplexity and Google documentation and from published studies; the weight of each check follows the strength of its evidence.
Structured data
Finds JSON-LD and checks it parses, uses the right types for the page (Organization, Service, Product, FAQPage) and doesn't contradict the visible text.
Meta tags
Title and description length, canonical, language, and a complete Open Graph set so the page is indexable and previews correctly.
Content structure
One H1, a sane heading hierarchy, an opening paragraph that answers “what is this page” in under 60 words, and a Q&A block with direct answers.
0–100 score
One score, four verdicts, then the fixes that matter
most.
Hard for AI to read (0–39) · Partly readable by AI (40–69) · Readable by AI (70–89) · Ready to be cited (90–100). Blockers first, then improvements. The score is a diagnostic guide, not a promise of inclusion or ranking.
How it works
Your audit stays in your browser
Open the extension on any page and start the check. It reads the page and the site's public files from your browser, then builds the report locally.

What next
Got a list of fixes? Two ways to clear it
Do it yourself
Each failed check links to a short explanation with the exact file or tag to change. Most fixes are a few lines in robots.txt, a corrected sitemap, a JSON-LD block or a rewritten opening paragraph.

FAQ
Quick answers
What does the checker measure?
Whether a page and its site files meet the documented preconditions for AI systems to access and interpret them: crawler permissions, valid files, structured data, complete metadata and readable structure. It does not query any AI assistant.
Is AI Visibility Checker free?
Yes. The Chrome extension is free to install and use, with no account.
What data does the extension collect?
None from the pages you audit. Checks run locally; the only network requests go to the audited site's own origin for robots.txt, sitemap.xml and llms.txt. Joining the waitlist submits your email to flowpro.dev, covered by the site privacy policy.
What is AI visibility?
Whether AI assistants such as ChatGPT, Claude, Perplexity and Gemini can access your pages, understand what your business does and use them as sources. The terms AEO and GEO describe the same work; there is no agreed definition, and Google treats it as part of SEO.
Will a high score get me cited?
Not by itself. A high score means your side is done: nothing technical stops an assistant from reading you. Mentions also depend on what other sites say about you and on each platform's own selection.
Which crawlers does it check?
GPTBot (OpenAI), ClaudeBot (Anthropic) and PerplexityBot are the ones whose block is reported as a failure: block them and those assistants cannot read the site at all. OAI-SearchBot, Claude-Web, Google-Extended, Bingbot, CCBot and Applebot-Extended are checked too and reported as a warning, because blocking them narrows where you can appear rather than shutting you out entirely.
