Crawlers and AI assistants
Every crawler may fetch every page. robots.txt allows all user agents and names the ones whose access matters most, so that the policy is explicit and a hosting provider’s default bot settings can be checked against it:
- Search engines, AI search and assistants fetching pages for their users: Googlebot, Bingbot, OAI-SearchBot, ChatGPT-User, Claude-SearchBot, Claude-User, PerplexityBot, Perplexity-User.
- AI training crawlers: GPTBot, ClaudeBot, Google-Extended, Applebot-Extended, CCBot. They are allowed as well: the guides are published for reuse under CC BY 4.0, with the attribution described above.
For agents and tools, /llms.txt indexes every guide’s Markdown version and the content API serves every guide as JSON. Preview copies of the site block all crawlers; this policy applies to the published site.
