Ignored robots.txt?

AI2Bot collects pages for model training. Training inclusion is not the same as being cited, so measure where AI answers actually cite your site before drawing conclusions from crawl logs.

    Allen Institute for AI publishes no IP ranges, reverse DNS or signatures for AI2Bot in the sources here, so it cannot be verified. Treat matches as unconfirmed.

How this is measured

Finalized daily crawler summaries from sites connected to Trakkr, grouped by the crawler named in each request. Trakkr’s own site is excluded. A site counts as reached in a week when it logged at least one request from AI2Bot. The typical figure is the median weekly requests among the sites it reached.

  • This is a sample of connected sites, not the whole web.
  • A matching user-agent does not prove the named operator sent the request.
  • Requests are not unique pages, training use or citations.
  • Crawlers seen on fewer than 10 sites are not shown. Classic search crawlers such as Googlebot are not collected on every site, so they are left out.
