Questions
- What is AI2Bot?
- The Allen Institute for AI's crawler, which finds documents for its open AI research and models. MetricRaven groups it under Training crawlers: crawlers collecting public pages that may be used to train AI models.
- How do I verify that a request really comes from AI2Bot?

- How do I block or allow AI2Bot?
- Add a robots.txt group for "AI2Bot" with the paths to allow or disallow. Fetchers that act for a user may ignore robots.txt; block those at your server or firewall instead.
- How can I see when AI2Bot visits my website?
- Most crawlers never run JavaScript, so browser analytics miss them. MetricRaven's @metricraven/ai-crawl package reports crawler requests from your server, verifies their IPs against published ranges, and shows which pages each crawler reads.
