Isgen AI Detector
What it is
Isgen AI Detector is a web and API service for assessing whether content may be AI-generated. It returns an overall Human, AI, and Mixed score, with sentence- and phrase-level findings shown through color-coded highlights. Users can paste text or upload files, either one at a time or in bulk. Isgen says the detector supports over 80 languages and is trained to identify output from ChatGPT, GPT-5, Claude, Gemini, DeepSeek, and Llama. The site also lists a plagiarism checker, grammar checker and proofreader, AI humanizer, AI editor, citation generator, image detector, and video detector. Its AI Editor combines drafting, editing, proofreading, humanizing, and live score updates, and the homepage says it can be started free without signing up. A free AI detector is included on Freemium. Paid plans start at $8/mo (annual). Isgen cautions that detector results are not fully accurate and advises educators not to penalize students based on them alone.
