Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.

A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
Side Reader is a Chrome extension that opens PDFs in the sidebar of ChatGPT, Claude and DeepSeek so you can read and interact with them side by side: summarize, translate, explain or ask about any passage without leaving the chat.
PDFs render directly in the sidebar next to the chat, so your document and the AI conversation are visible at the same time.
Summarize a whole document, translate it, or have passages explained in simpler terms using the AI you are already signed into.
Built-in buttons cover the common actions, and you can edit their prompts to make the AI respond in the format and tone you need.
Ask about charts, scans or regions that cannot be selected by taking a screenshot question instead.
