ChatBot Blocker by CellarWeb


You can block ChatGPT and Bard and other compatible AI scanners from using your site content by adding specific commands to your site’s virtual robots.txt file. Note that an actual robots.txt file in your site root will override the virtual commands.

The plugin also adds your sitemap.xml file to the virtual robots.txt file.

We’ll add them to the plugin when we find them. And the latest list will automatically be enabled by the plugin. Use the support pages for the plugin for requests.

Whare do I add more settings?

We recommend using WP standards to add to your virtual robots.txt file.

How do I see the actual virtual robots.txt file?

Use the URL of , replacing ‘’ with your actual site domain name. There is a link on the Settings, Reading screen under the virtual robots.txt box created by the plugin.

What if I have an actual (not virtual) robots.txt file in the root of my site?

The actual file will override any virtual settings. The screen will show a warning message below the display of the virtual settings if an actual file is found in the site’s root folder.

Why do I want a robots.txt file?

The robots.txt file is used by responsbile bots to scan only the files that you want to be scanned. The plugin adds commands to block the AI bots from scanning your site and using your content.

There might be some bots that ignore the robots.txt directives. This is not common, but there is no easy way to block those irresponsible bots.

Should I put SEO Optimization commands in the robots.txt file?

You could, but they won’t be effective. There are better ways to do SEO optimization.

Where can I learn more about how site crawlers work and how they use the robots.txt file?
