About Scribbr AI Detector
Scribbr AI Detector is a free web-based checker from Scribbr, the academic proofreading and citation company. It analyzes pasted text and classifies it as human-written, AI-generated or AI-refined, with paragraph-level feedback that points to the sections most likely to be machine-produced. Checks require no account, are unlimited in number, and accept up to 1,200 words per submission. Supported languages include English, German, French and Spanish, and Scribbr states that submitted texts are not stored or shared.
The tool targets students verifying coursework before submission and educators screening assignments, and it detects output from models such as ChatGPT, Gemini and Copilot. Scribbr publishes its own comparative research on AI detector accuracy and pairs the detector with related services, including a plagiarism checker, citation generator and proofreading. For longer documents or more advanced detection features, Scribbr directs users to QuillBot's AI detector, which shares its underlying technology family.
