# AI Detector

> AI-Detector.wiki is an AI detector and AI checker resource for reviewing text for patterns commonly associated with AI-generated writing from ChatGPT, Gemini, GPT-5, Claude, Grok, and other generative AI systems. Detection results are probabilistic review signals, not proof of authorship, and should be interpreted with human context, drafts, citations, revision history, and other evidence.

Primary language: English
Primary audience: students, educators, writers, editors, publishers, businesses, and website owners evaluating AI-writing signals.
