# AI2Bot

AI2Bot is Allen AI's training only crawler token. Blocking it costs nothing in the AI readiness score. 13.4% of the top 1,000 websites with a robots.txt block it.

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](https://allenai.org/crawler)
- **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](https://www.crawlreadiness.com/research/ai-crawler-access-october-2026).

## 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](https://www.crawlreadiness.com/tools/robots-txt) writes a whole file with the same split: block the training crawlers, keep the search and answer crawlers.
