Description
DetectGPT offers a free AI writing checker and plagiarism detection service, allowing users to analyze text for AI-generated content and identify similarities with public web pages. The tool enables users to paste up to 5,000 words or a public URL to receive an AI percentage score, indicating how much of the draft sounds machine-made. It highlights passages that appear stiff or AI-generated in yellow, orange, and red, providing a visual guide for editing.

Beyond AI detection, DetectGPT includes a plagiarism checker that identifies matching phrases on public web pages and lists source links. This feature helps users understand the overlap percentage of their pasted draft with existing online content. The service is independent and not affiliated with other tools like Turnitin or ZeroGPT, offering a distinct analysis.
DetectGPT is designed for a broad audience, including students, teachers, writers, and individuals writing in a second language. Students can use it for a private check before submitting papers, especially if they've used AI models for outlines. Teachers and writers can identify AI-generated phrasing in drafts before client or editor review. For second-language writers, it helps in varying rhythm and avoiding false alarms that can arise from careful, even prose.
The platform also provides a separate AI Humanizer tool, which allows users to rewrite AI-generated text to sound more natural. This tool accepts up to 1,000 words per run and aims to change the rhythm and stock phrasing while preserving the original meaning. It offers various modes like Standard, Fluent, Academic, Formal, Casual, and Concise, and supports multiple output languages. The humanizer is intended as an editing step to improve the cadence of AI-generated content, not as a guarantee to bypass detectors.
DetectGPT operates without requiring an account, card, or school login, making it accessible for quick, independent checks. Text pasted for AI detection is scored in the user's browser, with history staying on the device, ensuring privacy. For URL analysis, servers fetch the public page to read and score the text. The tool emphasizes that its scores are signals for editing rather than definitive verdicts of authorship or misconduct, encouraging users to rewrite stiff lines and understand that detectors do not share a universal percentage.
