CORPUSTool page
Free llms.txt generator and checker for business websites.
Paste a URL and Corpus Plan checks the AI-search basics around llms.txt: whether the file exists, whether the site has structured facts, and whether AI crawlers can read the pages.
No account or email needed for the first report. Pro is $99/mo for weekly monitoring and up to 10 sites.
What gets checked first
The free report checks /llms.txt, JSON-LD structured data, robots rules for AI crawlers, extractable content, and question-shaped headings. Missing llms.txt is treated as a small parity fix, not a promise of AI mentions.
What Pro adds
After you claim the workspace, Pro generates the ready-to-place llms.txt file from the audit context, then keeps the site on a weekly re-scan.
Best for
