The tool parses robots.txt files according to RFC 9309 standards, checking for longest-match Allow and Disallow precedence, and supports wildcard * and $ symbols. It provides recommendations for AI crawler configurations to optimize visibility and control over AI indexing and training.
One of the key benefits of this tool is its privacy feature; all data pasted into the tool remains within the user's browser, ensuring that no information is sent to external servers. This is particularly important given the security constraints imposed by CORS, which prevent automatic fetching of robots.txt files from different domains.
The tool also educates users on the implications of blocking certain AI crawlers. For instance, blocking GPTBot does not remove a site from ChatGPT search results, as ChatGPT uses a different agent, OAI-SearchBot, for search purposes. Additionally, the tool highlights the importance of understanding how different AI user agents respect or ignore robots.txt rules, providing insights into how to manage AI visibility effectively.
