The Allen Institute for AI's crawler, used to build open datasets such as Dolma that train its open language models.

Operated by Allen Institute for AI · Training crawler · operator documentation

3.76% block AI2Bot 938K of 24.91 million domains with a known robots.txt policy 0.27% block it by name 67,573 domains, the rest inherit a blanket * block 2.30% restrict it by name 574K domains name it and close some of its paths 2.65% name it in robots.txt 660K domains give it rules of their own

Data for Aug 2026. All four percentages divide by the same 24.91 million domains. Blocked counts both explicit User-agent: AI2Bot blocks and blanket * blocks the crawler inherits.

Historical mentions, HTTP Archive

Share of sites in each month's HTTP Archive crawl whose robots.txt named AI2Bot (or a legacy alias of it). This series counts mentions only (the archive keeps no rule text), comes from a different population than our own crawl above, and the two are never merged.

Sites whose robots.txt names AI2Bot (or a legacy alias) with a full block, ranked by Open Page Rank. Sites blocking every crawler with a blanket * rule are counted above but not listed here. Since dates start at our first observation of the rule.

Restricting some paths

Also matched via the legacy token ai2bot-dolma, which some sites still use for this crawler.
