This plugin is very simple: It adds a line of code in high priority to the header of every page on your site that politely asks AI crawlers not to use your content for AI training purposes. For more information on how it works, you can check out the blog post what is DeviantArt’s new “noai” and “noimageai” meta tag and how to install it.
All you need to do is upload it to the plugins section of your WordPress site and activate it. That’s it. Simply deactivate and delete it if you don’t want it anymore.
