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.
Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
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.

Open the toolbar popup, type your question, and Grok launches in a new tab with the prompt already filled in — Ctrl+Enter submits it instantly.
Type `grok`, hit space, and enter your prompt directly in the omnibox; Grok opens ready to run it without any clicking.
Highlight a passage on any page, right-click, and choose Grok to ask about exactly that text instead of retyping it.
An Ask Grok button appears on Google results and a Grokipedia bar on Wikipedia articles, so your current query or topic can jump straight into Grok. Both can be toggled off.
