Detect GPT is a Google Chrome extension that serves to identify and highlight AI-generated content as you navigate the internet. The primary functionality of this tool is to scan the content of the web pages and indicate whether the content present is AI-generated or human-written. The indication is provided through a change in icon color, providing a visual cue to the user regarding the nature of the content. It also features an option to check the authenticity of content. This is done by pasting any content into a form within the extension, which then analyses it. This tool is particularly useful for anyone who needs to discern human-authored text from AI-generated text in real-time, offering a quick and efficient method to verify the source of the content. Such a tool can be valuable in an era where AI-generated content is becoming increasingly prevalent. It is a free tool and can be installed directly from the Chrome web store with developer support accessible via GitHub.
