Origin by GPTZero is a plugin that can detect whether text was generated by AI on any website. Utilizing GPTZero's AI detection technology, it accurately identifies content created by AI language models such as ChatGPT, GPT-4, GPT-3.5, and GPT-3. You can use Origin by highlighting and right-clicking text or by copying and pasting text into the Origin text box. Additionally, the Origin plugin for Google Docs can verify the human authorship of documents by combining AI detection with document edit history playback to generate reports on human authorship. Origin is currently free to use.
