Isgen

Overview

Isgen is a multilingual-first artificial intelligence company dedicated to promoting transparency by enabling everyone to validate AI-generated content. At its core, Isgen offers an advanced AI detection platform that accurately identifies text produced by virtually every major large language model, including ChatGPT, GPT-5, Claude AI, Gemini, Microsoft Copilot, LLaMa, Grok, Mistral, DeepSeek, and Qwen. The tool boasts a benchmark accuracy of 96.4% with a near-zero false positive ratio, significantly outperforming other widely used AI detectors in the market. By employing an ensemble of state-of-the-art AI systems and sophisticated language understanding algorithms trained on millions of samples, Isgen provides unprecedented precision in distinguishing between AI-written and human-authored content.

Unlike many AI checkers that only support English or a handful of languages with limited reliability, Isgen stands out with native support for over 80 languages. This multilingual capability is powered by models that automatically detect the input language and apply the relevant detection pipeline. The platform's deep insights engine provides granular, interpretable results through color-coded highlights, sentence-level analysis, and phrase-level breakdowns. Users can see exactly which sentences in a text are classified as AI, Mixed, or Human, along with individual AI Impact scores that indicate the degree to which each part of the text contributes to the overall detection result. This interpretability is critical for educators and content developers who need to understand not just whether a piece is AI-generated, but precisely why and where.

Beyond detection, Isgen offers a comprehensive suite of writing and integrity tools. The integrated AI Editor enables users to draft, edit, proofread, and check their AI score in real time within a single interface, eliminating the need to switch between multiple applications. The platform also includes a plagiarism checker, an AI grammar checker with proofreading capabilities, an AI humanizer to refine machine-generated text into more natural writing, and an AI citation generator. Bulk scanning and batch file uploads make the tool suitable for large-scale content review, while document history (available on paid plans) provides a convenient record of prior scans. Isgen is committed to data privacy, with no data storage for standard scans and user-controllable deletion of history for paid subscribers.

Trusted by over one million users with a 4.9 rating, Isgen is used by educators to maintain academic integrity, by content creators to ensure authenticity, and by businesses to safeguard the credibility of their multilingual publications. With flexible pricing plans—including Academic, Writing, and Ultimate tiers—plus an API for enterprise integration, Isgen delivers a scalable, transparent, and highly accurate AI detection solution for a global audience.
