Description
Isgen is a multilingual-first AI detector built to validate whether content was written by a human or an AI model. It analyzes text with machine learning models trained on millions of samples, examining sentence structure, word choices and patterns to assign each phrase a probability that it was AI-generated or human-written. Detailed insights highlight, down to the sentence and phrase level, which parts are perceived as AI and how they affect the overall AI score, so writers can pinpoint and revise those sections.

The detector covers text from closed and open-source models including GPT-5, ChatGPT, Claude, Gemini, Microsoft Copilot, LLaMA, Grok, Mistral, DeepSeek and Qwen, and it can identify mixed human and AI content. Isgen reports a benchmark accuracy of 96.4% with a near-zero false-positive ratio and works across more than 80 languages. You can paste text, upload a file, or provide a URL, and it does not store data (input history is kept only for paid users and can be deleted anytime).
Beyond detection, Isgen offers a premium suite including a plagiarism checker, grammar checker and proofreader, an AI Editor that lets you draft, edit and see your AI score update in real time and humanize robotic text, plus an AI humanizer and citation generator on higher tiers. Free AI detection is available up to 5,000 characters with no sign-up. It is aimed at students, researchers, educators, content creators, journalists and professional writers.
