Free website diagnostic tools
Check how your website is configured and described for AI discovery
Choose a check, enter the domain or page URL that tool requests, and review the exact public rules, files, page content, or identity signals found on your website. Each result explains what was observed and what to review next.

robots.txt checker
Enter a public hostname to test whether its deployed robots.txt policy allows, blocks, or has no matching restriction for documented AI crawler tokens at the root path.
Content
llms.txt diagnostic
Check the live /llms.txt file on a public website, or paste a draft to validate it before deployment. Both modes use the same rules for title, introduction, sections, links, malformed Markdown, duplicate destinations, and insecure URLs.
Identity
Website identity diagnostic
Compare visible homepage identity with structured entities, graph identifiers, sameAs identity references, and public trust signals.
Structure
Recipe schema checker
Enter a public recipe page URL to inspect its Recipe JSON-LD against current Google-required fields and a focused set of recommended properties.
Build
llms.txt generator
Fill in a title, short context, and the resource links you want to list, and this page builds a valid llms.txt file for you to review, edit, and publish.
Build
robots.txt generator
Choose a declared policy goal and this page builds robots.txt groups for the documented AI crawler tokens that goal has an explicit preference for, which you can review, edit, and publish.
Build
JSON-LD generator
Build a starting Organization JSON-LD block with a stable #organization identifier plus optional logo and sameAs identity references.
Compare
AI citation forensics
Paste a prompt and the source an AI answer cited. See which public evidence differs from your site, what is worth testing, and what no external audit can prove.
Identity
Business facts consistency
Compare the business name, phone, email, address, and official profiles stated on your homepage, About page, Contact page, and JSON-LD, and see where any value differs.
Compare
Launch and migration check
Compare the new version of a site or page with the current live one under the same audit rules, and see regressions in crawler access, content, and identity before you launch.
