Enter a page address. The tool checks whether the crawlers behind ChatGPT, Claude, Perplexity and Google are allowed to read it, and whether its content is in the HTML without JavaScript.
Three things to keep in mind when you read the report.
Blocking a training crawler such as GPTBot, ClaudeBot or Google-Extended is an editorial choice. Blocking a search crawler such as OAI-SearchBot, Claude-SearchBot or PerplexityBot removes the page from answers that cite their sources.
Several AI crawlers read the HTML as the server sends it, without running JavaScript. Text loaded afterwards by the browser can stay invisible to them.
It reads a single page, with its own crawler. A firewall may answer real AI crawlers differently: server logs remain the reference.
