Detect GPT
DetectGPT: Chrome Extension to Spot AI-Generated Text
DetectGPT is a free Chrome extension that scans webpages or pasted text to flag content generated by AI tools like ChatGPT and GPT-3.
Overview
DetectGPT is a lightweight Chrome extension built for anyone who needs to quickly determine whether written content was produced by a human or an AI model. As AI writing tools become more common, distinguishing authentic content from machine-generated text has become a real challenge for publishers, educators, and researchers alike. DetectGPT tackles this by scanning text directly in your browser and comparing it against patterns typical of models like ChatGPT, GPT-3.5, GPT-3, GPT-J, GPT-NEO, and GPT-2.
The tool offers two simple detection modes: a manual check where you paste or right-click selected text to run a scan, and an automatic page scan that analyzes the content of any webpage you're currently viewing with a single click. There's no signup, login, or account creation required, making it an accessible, frictionless option for anyone who needs quick answers about content authenticity. Whether you're vetting search results, reviewing submitted articles, or double-checking your own site's content, DetectGPT provides a fast first-pass signal on AI involvement.
