What Isgen AI Detector is
Isgen AI Detector is a web and API service for assessing whether content may have been generated by AI. It gives an overall Human, AI, and Mixed score, with sentence- and phrase-level analysis shown through color-coded highlights. Users can paste text or upload files, including multiple files for bulk scanning. Isgen says the detector supports over 80 languages and is trained to recognize output from models such as ChatGPT, GPT-5, Claude, Gemini, DeepSeek, and Llama. Its wider tool set includes plagiarism checking, grammar checking and proofreading, an AI humanizer and editor, citation generation, image and video detection, and bulk scanning. The AI Editor combines drafting, editing, proofreading, humanizing, and live AI score updates; the homepage says it can be started free without signing up. A free detector is available. Academic costs $8 a month billed annually, while Ultimate costs $24 a month billed annually. Isgen cautions that detector results are not fully accurate and should not be the sole basis for penalizing students.
