AI Crawler User Agents and robots.txt Tokens
A reference list of 27 AI and search crawlers (GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, Claude-SearchBot, PerplexityBot, Google-Extended, Applebot-Extended, meta-externalagent, CCBot, Amazonbot, DuckAssistBot, MistralAI crawlers, Bingbot and more) with the exact robots.txt token, who runs it, what it is for, whether it follows robots.txt, whether the data is used for AI training and what happens if you block it. Every row links to the operator's own documentation.
The key idea: AI crawlers are not one thing. Training crawlers, AI search crawlers and user-triggered fetchers do different jobs. Blocking a training crawler (for example GPTBot) does not remove a site from that company's AI search, while blocking a search crawler (for example OAI-SearchBot or PerplexityBot) can stop a site from being cited in AI answers.

Columns
| Column | Description |
|---|---|
id |
Row number |
robots_token |
The name to use in a robots.txt User-agent: line |
operator |
Company or organisation that runs the crawler |
category |
AI training, AI search index, User-triggered fetch, Search engine crawler, Control token (no crawler), Link preview, and others |
purpose |
What the crawler does, summarised from the operator's documentation |
respects_robots_txt |
Whether the operator says it follows robots.txt |
used_for_ai_training |
Yes, No, May be, Indirect or Not stated, per the operator's documentation |
effect_if_disallowed |
Practical effect of blocking it in robots.txt |
docs_url |
Operator documentation used as the source |
ip_list_url |
Published IP range list, where the operator provides one |
last_verified |
Date the row was checked against the source |
Intended use
- Writing a robots.txt policy that keeps AI search visibility while opting out of model training
- Auditing websites for GEO (generative engine optimization) and AI search readiness
- Bot detection, log analysis and allow lists
Limitations
- Crawler names, purposes and policies change. Rows were checked against operator documentation on the
last_verifieddate; confirm with the linked source before relying on a row. - "Not stated" means the operator's documentation did not say. It is not a claim either way.
- User-triggered fetchers (ChatGPT-User, Perplexity-User, Amzn-User, meta-externalfetcher) may not follow robots.txt because a person requested the page.
- User agent strings can be spoofed. Verify important traffic with the operator's IP lists or reverse DNS.
- Crawlers without public operator documentation are not included.
