What it is

Isgen AI Detector is a web and API service for assessing whether content may be AI-generated. Its detector reports overall Human, AI, and Mixed scores, with sentence-level and phrase-level analysis shown through color-coded highlights. Users can paste text or upload files individually or in bulk. Isgen says the detector supports more than 80 languages and identifies outputs from models including ChatGPT, GPT-5, Claude, Gemini, DeepSeek, and Llama. The site also lists plagiarism, grammar, proofreading, humanizing, editing, citation, image-detection, and video-detection tools. Its AI Editor combines drafting, editing, proofreading, humanizing, and live AI score updates, and can be started free without signing up. Freemium includes a free detector. Academic costs $8 a month billed annually, Ultimate costs $24 a month billed annually, and Writing costs $15 a month billed annually. Isgen warns that detector results are not fully accurate.
