AI Crawler Access Checker
AI assistants use separate crawlers for model training, for search results and for fetching pages on a user's request. This check reads the site's robots.txt and reports, bot by bot, whether each one may access the homepage.
Results open in the site's full report, which you can share, compare and re-run.
What it checks
- OpenAI: GPTBot, OAI-SearchBot, ChatGPT-User
- Anthropic: ClaudeBot, Claude-SearchBot, Claude-User

Frequently asked questions
- Should I block AI crawlers?
- It depends on your goals. Blocking training crawlers such as GPTBot or CCBot keeps content out of future models, while blocking search crawlers such as OAI-SearchBot or PerplexityBot can remove you from AI answers and their citations.
- Does allowing a bot guarantee visibility in AI answers?
- No. Access is a prerequisite, not a ranking signal. The report's GEO readiness score covers the other technical signals.
- Is robots.txt enforced?
- robots.txt is a voluntary standard. The major operators listed here document that their crawlers honor it.
