How do AI Detector Chrome Extensions Work?

An AI Detector is a tool that allows you to tell whether a text was written by AI or by a person. It can also assess the origin of your image(s) and photos, and provide a complete forensics analysis including C2PA and IPTC watermarks, and full Exif details.

Chrome Extensions allow you to use a tool on any webpage while using the web browser Chrome (developed by Google).

This is very helpful for users of AI detectors as it means they can check writing or images on any website they are working on.

For example, a student might be writing an assignment on Google Docs and a teacher can then check the text with a Chrome extension to see if they used ChatGPT.

Who is this Chrome Extension For?

An AI-detecting Chrome Extension is good for anybody who needs to know whether content was written by AI or a person.

Let’s look at two examples: Teachers and Publishers

Teachers need to know if their students are using an AI tool like ChatGPT to do their homework. There are two ways that students can use AI, either copy/paste directly from their AI tool or use AI to improve their work. 

It is a complete waste of time for a teacher to correct an essay written by ChatGPT and AI detectors can help stop that. 

Online Publishers also need an AI detector as they may not want their writers to use AI in their content. AI can often get things wrong and it is easier to be careless when you don’t write every word yourself.
