AI2Bot
Explores certain domains to find web content used to train the Allen Institute's open language models.
Where this comes from
- Documented by the vendor. Source: allenai.org
- Honours robots.txt.
- Listed, not scored. It cannot keep a site out of today's answers, so the check shows a block without deducting for it.
In the top 1,000 websites
- 13.4% block it in robots.txt (76 of the 569 sites with a robots.txt), as of 2026-10-12.
- Method, limits and the full data: the October 2026 study of the top 1,000 websites.
What blocking it costs
Nothing in today's answers, and nothing in the readiness score: AI2Bot only gathers training data, so blocking it is a policy choice about future models, not about being found. The check lists the block without deducting for it.
The robots.txt lines
To let it in (a group that names the crawler replaces any wildcard rules for it, so this also lifts a User-agent: * block):
User-agent: AI2Bot
Allow: /To keep it out:
User-agent: AI2Bot
Disallow: /A rule in robots.txt is a request. Allen AI says this crawler honours it. The robots.txt generator writes a whole file with the same split: block the training crawlers, keep the search and answer crawlers.
