 tool for estimating how much of a piece of writing appears to have been generated by AI. It breaks a document into smaller sections and analyzes language patterns, syntax, sentence structure, and complexity before producing a percentage score for the text. It can identify writing associated with models such as ChatGPT, Claude, and Gemini.

The detector is built into Grammarly’s writing environment rather than existing only as a standalone checker. Depending on the Grammarly plan and product being used, it can be accessed in Grammarly Docs, Google Docs, Microsoft Word, and through Grammarly’s desktop and browser tools. The results can show which sections are more likely to be flagged as AI-generated.

Grammarly also connects AI detection with its broader originality tools. Users can combine detection with plagiarism checking, citations, and Grammarly Authorship, which records how a document was created, including text that was typed, pasted, generated with AI, or edited with Grammarly.
