ภาพรวม AI Crawler Rules: robots.txt Check and Build
Reads your robots.txt, 21 AI and search bots
Shows allowed or blocked, with the rule line
Builds lines to paste, with a diff to review
Checks if llms.txt exists and its size
AI Crawler Rules reads your site's robots.txt and tells you, in plain words, which AI and search crawlers it allows or blocks: GPTBot, ChatGPT-User, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot, Googlebot, Bingbot and more (21 in all). For your home page and sample pages you type, it shows the answer and the exact line of your file that decides it (standard: RFC 9309).
Then build your rules: set Allow or Block per crawler, or use a preset (allow all, block training only, block all AI). You get the exact lines to paste, added to your current file without duplicate groups, with a diff and a copy button. It also reports whether /llms.txt exists and its size.
Each crawler shows its operator and purpose. The list is dated: check each operator's documentation.
No page limits, no watermark, no sign-up. Results stay in your browser tab.
Honest limits: a robots.txt rule is a request, not enforcement; some crawlers ignore it. Blocking search crawlers can remove your site from AI answers; the choice is yours, and nothing here promises traffic or AI visibility. The app cannot change your file: you paste the result in yourself.
