Ai2 Deep Research: User Agent, robots.txt Rules & Safety

Q: What user-agent string does Ai2 Deep Research use?

Ai2 Deep Research is reported to identify itself with AI2Bot-DeepResearchEval. That spelling comes from ai.robots.txt, not from Allen Institute for AI, which has not published crawler documentation naming it. Use it in robots.txt as the best available match, and treat a request carrying it as a clue rather than proof of who sent it.

Q: Is Ai2 Deep Research safe?

Ai2 Deep Research is rated Safe in this directory, meaning there are no credible public reports of abusive crawling under this name. It is a Reported token: Allen Institute for AI has not published documentation for it, so its purpose, crawl rate and robots.txt behaviour are not confirmed by the operator, and anyone can send the same user-agent string. Allow or block it on its stated purpose, and back the robots.txt rule with a firewall rule if the traffic matters to you.

Q: Will blocking Ai2 Deep Research hurt my SEO?

✅ No SEO Impact - Blocking Ai2 Deep Research does not affect your rankings in Google, Bing, or any other search engine. Ai2 Deep Research is an AI crawler, not a traditional search indexer. You can freely block it via User-agent / Disallow: / without any SEO penalty.

Q: How do I block Ai2 Deep Research in robots.txt?

Add the following lines to your /robots.txt file: User-agent: AI2Bot-DeepResearchEval Disallow: / This instructs Ai2 Deep Research not to crawl any path on your site. To block only specific sections, replace / with the path (e.g., Disallow: /blog/).

Q: How do I verify if Ai2 Deep Research is crawling my site?

Search your access logs for AI2Bot-DeepResearchEval (for example grep -i "AI2Bot-DeepResearchEval" /var/log/nginx/access.log). Because the operator publishes no IP ranges or reverse-DNS pattern, a match shows that something used the name, not that Allen Institute for AI sent it.

Reported, not operator documented

Allen Institute for AI has not published a crawler page that names AI2Bot-DeepResearchEval. It is listed here because a credible public source does: ai.robots.txt. Reported AI2 evaluation crawler; AI2's page names only AI2Bot.

What that means for you: the robots.txt rule on this page is the best available spelling, and a well-behaved crawler using this string will honour it, but there is no vendor statement of purpose, crawl rate or robots.txt compliance to rely on. Treat a matching request in your logs as a detection clue, not proof of who sent it, and combine the rule with a firewall rule if the traffic matters to you. If the operator publishes documentation, this profile moves to Official docs.
