What the AI Crawler Checker Tests
The checker reads the public robots.txt file for the submitted website and evaluates crawler directives for common AI and search user-agents. It helps surface an accidental block that could prevent a crawler from requesting content.
AI Crawlers and Search Crawlers
Different services use different user-agents and may use them for different purposes. A rule that allows Googlebot does not automatically describe access for GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot or Google-Extended, so each relevant directive should be reviewed separately.
What an Allowed Result Means
Allowed means the inspected robots.txt rules do not block that crawler for the tested location. It does not mean the service will definitely crawl, index, train on, quote or cite the page. Those decisions are controlled by the external platform.
When to Review robots.txt
Check crawler access after a redesign, migration, staging-to-production launch, security change or robots.txt edit. An unintended Disallow rule can remain unnoticed because the website still looks normal to human visitors.

Frequently Asked Questions
What does the AI Crawler Checker test?
It reads public robots.txt directives and evaluates how rules apply to common AI and search crawler user-agents such as GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended and Googlebot.
Does allowing an AI crawler guarantee AI visibility?
No. Crawler permission only removes one possible access restriction. Retrieval, indexing, training policies, answer selection and citations are controlled independently by each platform.
Can robots.txt completely prevent content from appearing elsewhere?
Robots.txt is a crawl-control mechanism, not a universal content-removal system. Platforms may have different user-agents and policies, so review the documentation of services that matter to you.
What is the difference between GPTBot and OAI-SearchBot?
Crawler names can represent different product purposes and policies. Treat each user-agent according to the current documentation of the service you want to allow or restrict rather than assuming all AI crawlers behave identically.
Can different AI crawlers have different robots.txt rules?
Yes. robots.txt can define separate user-agent groups, allowing a site to set different crawl rules for different named crawlers.
