Are AI Crawlers blocked from your site? Instantly find out

Use this tool to check if your website’s robots.txt is configured to allow or block popular AI crawlers.
Quickly verify your site’s current AI access settings like GPTBot, ClaudeBot, and others.

Check robots.txt for AI Bot Blocks

Enter your domain:

What is robots.txt?

robots.txt is a standard file used to tell crawlers which parts of your site they’re allowed to access. It’s placed at the root of your domain—like https://yoursite.com/robots.txt. Originally designed for search engines, it’s now also used to block AI bots like GPTBot, ClaudeBot and others. Whether or not you want AI tools reading your content, robots.txt gives you a say. You can allow some, block others, or shut them all out entirely.

How do you block AI bots?

To block AI bots, you just add rules to your robots.txt file. For example:

User-agent: GPTBot
Disallow: /

User-agent: ClaudeBot
Disallow: /

This tells those bots to stay out. You can block one, many, or all at once.

Do you really want to block them?

That depends. Blocking AI bots protects your content from being used to train models or served elsewhere without credit. But it also means losing visibility in tools that might surface your site in AI-driven answers or summaries.

There’s no single right answer — it’s about what matters more to you: control or reach.
