About DetectGPT

DetectGPT is an AI detector and humanizer focused on telling human writing apart from text generated by large language models such as ChatGPT, GPT‑4, Gemini, Claude, and others. It analyzes text for AI‑like patterns, plagiarism, factual accuracy, and readability, while also offering tools to rewrite AI content so it appears human written. The product targets educators, students, writers, and organizations that care about content authenticity, but also those who need to reduce the chance of being flagged by AI detectors. Key Features: AI Text Detection Across Models: Classifies text as human, AI, or mixed and provides probability scores, trained on billions of words and tuned for modern models like GPT‑4 and Gemini. Original Content Certification: Issues human‑written certificates and shareable analysis links so agencies, freelancers, and publishers can prove authorship to clients and stakeholders. Plagiarism, Fact Check, and Readability: Built‑in plagiarism checks against online sources, basic fact verification, and readability scoring to strengthen the integrity and clarity of each piece. AI Content Humanizer: Rewrites AI‑generated text to preserve meaning while altering style and structure, aiming to bypass AI detectors, including its own. Multi‑Language Support: Works in 50+ languages, helpful for global classrooms and international content teams. File and Batch Processing: Upload documents and run batch scans (with quotas based on plan) plus export PDF reports for audit trails and compliance. AI Detection & Humanization API: REST API to embed detection and humanization directly into custom platforms, LMSs, or internal tooling.
