The AI-Visibility Honor Roll: 353 sites fully open to AI search

This is the elite intersection of two separate signals this property already measures: a valid llms.txt file, and zero robots.txt blocks on the three crawlers that feed AI answer citations (OAI-SearchBot for ChatGPT, PerplexityBot for Perplexity, Claude-SearchBot for Claude). 373 of the 4,999 sites in the census have a valid llms.txt at all; of those, 353 also allow all three AI search crawlers in. That is 353 out of 4,999, or 7.1%, of the entire census -- fully AI-visible by both measures at once.

Being on this list does not require having an llms.txt AND being blocked-free by accident: both facts are measured live and independently, the same way every other page on this property works. 14 sites in the llms.txt set were excluded because their robots.txt could not be read or confirmed in the census, not because they failed -- an unknown is never counted as a pass here.

Each site links to its own live AI visibility result, and carries a copyable badge (drawn fresh from a live check every time it loads, so it can never go stale the way a static image would). Measured on 2026-09-07 against each site's live robots.txt, using the same matcher Google publishes; llms.txt inventory from 2026-09-06. Raw data: the census page and the open dataset.
