DetectGPT

DetectGPT is a Chrome extension designed to help users identify AI-generated text, particularly content produced by models like ChatGPT, as they browse the web. Once installed, the extension analyzes selected text on webpages and provides an assessment of whether the content is likely written by an AI system or a human author. It typically works via a right-click context menu or extension popup, allowing quick checks without leaving the page.

This makes it useful for educators reviewing student work, content reviewers verifying originality, journalists and researchers evaluating sources, and general users curious about the authenticity of online information. DetectGPT focuses on text-based content and uses statistical or model-based signals to estimate the likelihood of AI authorship, returning a probability or qualitative verdict.
