Training crawlers

AI2Bot

AI2Bot is a bot operated by Ai2 that collects pages used to train AI models. Explores 'certain domains' to find web content. It is documented as honouring robots.txt, but no IP range list or reverse-DNS convention is published, so a request carrying this user agent cannot be proven genuine.

Also seen as Ai2Bot-Dolma. Rules need to cover every token.

AI2Bot at a glance

Reference data for the AI2Bot crawler
User agentAI2Bot

Token only. The operator has not published a full user-agent string, so match on the substring rather than an exact header.

OperatorAi2
PurposeContent is used to train open language models.
Respects robots.txtYes, documented
Verification methodNone published, user agent only

Ai2 documents the crawler and an opt-out but publishes no address list. Its output feeds the open OLMo and Dolma datasets, so a block here removes the site from public research corpora as well as from a model.

robots.txt

Allow or block AI2Bot

Paste one of these into the robots.txt file at the root of your domain. Rules are per token, so a block on one crawler leaves every other bot untouched.

Block AI2Bot
User-agent: AI2Bot
User-agent: Ai2Bot-Dolma
Disallow: /

Blocks every path for this crawler only.

Allow AI2Bot
User-agent: AI2Bot
User-agent: Ai2Bot-Dolma
Allow: /

Explicit allow. Useful when a wildcard rule above it would otherwise catch this crawler.

Allow, except the pages you never want quoted
User-agent: AI2Bot
User-agent: Ai2Bot-Dolma
Allow: /
Disallow: /account/
Disallow: /checkout/
Disallow: /search

Edit the Disallow paths to match your own account, checkout and search URLs.

What blocking actually costs you

Blocking AI2Bot keeps your pages out of the next training run. It does not remove anything already collected, and it has no effect on how the site ranks in ordinary search.

Block every crawler in the directory at once
Verification

Is that really AI2Bot?

A user-agent header is a string the client chooses. Scrapers copy AI2Bot precisely because site owners allow it. Ai2 documents the crawler and an opt-out but publishes no address list. Its output feeds the open OLMo and Dolma datasets, so a block here removes the site from public research corpora as well as from a model.

Paste the IP address from your access log below. You will see whether it belongs to a hosting provider, a residential proxy pool or a Tor exit, plus the ASN that announces it, which is what tells you whether the claim holds up.
