Tools (7)

scan_siteRun a live AI-accessibility audit of a domain: robots.txt policy for every tracked AI crawler, live user-agent probes, JavaScript-free readability, structured data and llms.txt. Returns a score out of 100 with per-check detail.
site_reportReturn the most recent stored audit for a domain without triggering a new scan. Faster and free of load on the target site.
census_statsCorpus-level statistics: how many measured domains block each AI crawler, mean access score, llms.txt adoption.
