Block Chat GPT via robots.txt


This plugin adds lines to the virtual robots.txt file that WordPress creates automagically if the file is not present physically on the server to block the OpenAI ChatGPT-User bot that is used by plugins in ChatGPT to crawl websites. Here is the information about the ChatGPT-User bot. It also blocks the the GPTBot user agent that may potentially be used to improve future models.

Please be aware of what this plugin does exactly: If you activate the plugin it will add some lines to the robots.txt file to tell Open AI Chat GPT bots (ChatGPT-User + GPTBot) to not to crawl and index parts of this website.

Please only activate this plugin if you know what you’re doing.

What can I do with this plugin?

This plugin adds the necessary lines to the virtual robots.txt file that WordPress creates automagically to block the OpenAI ChatGPT-User bot that is used by plugins in ChatGPT to crawl websites + the GPTBot user agent that may potentially be used to improve future models.

What ideas is this plugin based on?

None. After the launch of the OpenAI ChatGTP plugins that crawl websites, we needed a fast solution to add these lines to the robots.txt file and this was the solution we coded.

In August 2023 OpenAI added information about the GPTBot so we added this user-agent to the plugin.

What is the robots.txt file?

The robots.txt file is a plain text file located at the root folder of a domain (or subdomain) which tells web crawlers (like Googlebot) what parts of the website they should access and index.

The first thing a search engine crawler looks at when it is visiting a page is the robots.txt file and it controls how search engine spiders see and interact with the web pages.

System requirements

PHP version 7.4 or greater.
We require 7.4 or higher because we believe that everybody should be running a modern PHP version. When releasing this plugin WordPress recommends PHP 7.4 or higher. We would recommend 8.0 or higher as 7.4 has no security updates since 28 Nov 2022.

Întrebări frecvente

Why did you make this plugin?

We created this plugin to be able to append the lines to block the access of the OpenAI ChatGPT-User bot to the website via robots.txt without having to upload a robots.txt file.

Does Block Chat GPT via robots.txt make changes to the database?

No. The plugin doesn’t write any options or settings to the database.

How can I check out if the plugin works for me?

Install and activate. Have a look at the content of the robots.txt file in root of the domain.

How can I remove Block Chat GPT via robots.txt?

You can simply activate, deactivate or delete it in your plugin management section. There are no options stored in the database so you can delete it also via FTP and everything will be removed.

What happens if there is a physical robots.txt file on the server?

This plugin makes changes to the virtual robots.txt file generated automagically by WordPress and doesn’t work with a physical robots.txt file. In order to use this plugin you need to remove the physical robots.txt file from your server. Please delete the robots.txt file via FTP or Server Panel before using this plugin. We check this on activation (and only on activation). If we find a physical robots.txt file the plugin can’t be activated until the file is removed. Please keep in mind that we only check it on plugin activation and after activation we don’t check it any more; so if you upload a robots.txt file to the root of the domain once the plugin is activated, the plugin will have no effects but you will not receive a warning.

What happens if WordPress is installed in a subdirectory?

WordPress must be installed in top-level directory of the web server. Please note that the robots.txt must be in the top-level directory of your web server. If WordPress is installed in a subdirectory this plugin will not be effective because the robots.txt file generated by WordPress in the subdirectory will be ignored by the bots. Please note that we don\’t check this. You can read more about the robots.txt standard here How to create a /robots.txt file and Where to put it.

Are there any known incompatibilities?

Please don’t use it with WordPress MultiSite, as it has not been tested.

The plugin has similar functionality as the Virtual Robots.txt and the Better Robots.txt Index, Rank & SEO booster plugin; both are not compatible with our plugin as they remove all the virtual WordPress robots.txt content and create their own. The directives our plugin creates are not added to the robots.txt file these plugins generate as they don’t use the standard functions of WordPress to append information to them.

What lines does this plugin add to the robots.txt file?

User-agent: ChatGPT-User
Disallow: /
User-agent: GPTBot
Disallow: /

Are there any server requirements?

Yes. The plugin requires a PHP version 7.4 or higher and we recommend using PHP version 7.4 or higher. The plugin has been tested with PHP up to 7.4. When releasing this plugin WordPress recommends PHP 7.4 or higher.

Do you make use of Block Chat GPT via robots.txt yourself?

Of course we do. That’s why we created it. 😉
