[Read about it here.](https://www.pangram.com/blog/introducing-pangram-4)\n\nDetect AI-generated content with 99.98% accuracy. Trusted by universities, schools, and enterprises worldwide.\n\nProven the **most reliable and accurate** AI detector on the market by [third party researchers](/blog/third-party-pangram-evals), including the University of Maryland and the University of Chicago.\n\nAI writing contains structural, stylistic, and semantic patterns that can all be detected by a trained eye or sufficiently sophisticated detection software. AI detection is not magic. It can actually work.\n\nPangram's AI detector uses natural language processing and a massive data set of human and AI writing to analyze patterns in AI generated text created by popular models like ChatGPT, Gemini, Grok, Llama and Claude.\n\nPangram's accuracy leads the industry and has been [verified by researchers](/blog/third-party-pangram-evals) at the University of Chicago and University of Maryland.\n\nIn an era where AI-generated content is increasingly prevalent in academia, media, and business, the ability to distinguish between human and machine-authored text is critical. In education, it creates trust between students and teachers. It's important in journalism where integrity is essential. AI-generated text isn't inherently bad. However, society can benefit from being able to distinguish between AI and human text.\n\nOur product\n\nPangram combines cutting-edge AI and comprehensive plagiarism detection to give you the complete picture of text authenticity and get the information you need, all in one place.\n\nPangram won't just tell you how confident it is that the document is AI, but also how much of it is.\n\nPangram will highlight segments that have been edited by AI rather than fully AI-generated.\n\nCheck for plagiarism and AI all at once. Perform an AI plagiarism check with one click.\n\nFeatures\n\nThere are many AI detectors available, but Pangram is different. It actually works. We also provide advanced features backed by peer-reviewed research that allow users to understand the origin of a piece of writing.\n\nUses proprietary technology with years of research and development behind it, not an open source model or commercial LLMs covered with branding.\n\nPangram relies on diverse datasets, hard negative mining, and active learning to achieve industry-leading FPRs rather than perplexity and burstiness, which often fail in practice.\n\nPangram can detect content from all major language models including ChatGPT, Claude, Gemini, Llama and more, making it a comprehensive solution for AI detection.\n\nOur AI detection works across more than 20 languages, making it a truly global, multilingual solution for institutions and businesses worldwide.\n\nIndependent studies have shown that Pangram's AI detection outperforms trained human readers in identifying AI-generated content.\n\nPangram can detect AI-generated text even after it has been \"humanized,\" or processed by tools that attempt to evade AI detection, ensuring reliable detection.\n\nOur accuracy and reliability have been [independently verified](/blog/third-party-pangram-evals) by third-party researchers and educational institutions.\n\nWho we are\n\nAt Pangram, our mission is to rebuild trust amidst the increase in generative AI content. Founded in Brooklyn, NY, in 2023 by AI researchers from Tesla and Google, we continue to contribute to the research community to increase transparency.

Much better than other AI detection tools (by a country mile). I've used it and tested it thoroughly and seen minimal false positives and negatives.\n\nUniversity of Chicago Booth School of Business\n\nFor me, Pangram Labs has become the most student-centered option I’ve found for my courses. Students see the same report I see, directly in our Canvas shell, and Pangram’s documented false-positive rate (1 in 10,000) allows me to comfortably treat a flag as an invitation to talk, never as a presumption of guilt.\n\n— Susan Ray, Associate Professor Of English, Delaware County Community College\n\nThere's a lot of overhyped, me-too products flooding the AI space, but this detector is almost supernaturally good. I have yet to experience a single false positive or false negative.\n\nCloud Architect\n\n— Ryan Nicolace, Cloud Architect\n\nJenna Russell, PhD\n\nWe compare human experts with five AI detectors, including Pangram and GPTZero. Among automatic detectors, Pangram significantly outperforms the rest.\n\nTuhin Chakrabarty, Professor\n\nPangram is really one of the best AI detectors we have, and y'all should use it.\n\nBased on our experiences in the fall term, we have high confidence in Pangram as a detector of AI content in Wikipedia articles.\n\n— LiAnna Davis, Chief Programs Officer and Deputy Director at Wiki Education\n\nPangram noticeably outperforms other LLM content detection services I've tried. It reduces our moderation workload enough to pay for itself many times over. If you run a platform with user-generated content, you should probably be using it.\n\n— Robert Mushkatblat, CTO LessWrong\n\nDan Simon, CEO of Qwoted\n\nThe future of journalism depends on trust. This is why we're delighted to be partnering with Pangram, which has set the gold standard for Al detection and attribution\n\nOur model\n\nHow does Pangram achieve these results? [Learn more.](/research/how-it-works)\n\nOur classifier uses a traditional language model architecture. It receives input text and tokenizes it. Then, the model turns each token into an embedding, which is a vector of numbers representing the meaning of each token. The input is passed through the neural network, producing an output vector. A classifier head transforms the output vector into a prediction of human, AI, or AI-assisted. We train an initial model on a small but diverse dataset of approximately 1 million documents composed of publicly licensed human-written text. The dataset also includes AI-generated text produced by GPT-5 and other frontier language models. The result of training is a neural network capable of reliably predicting whether text was authored by human or AI.\n\nAfter the initial training, our model undergoes continuous improvement through iterative refinement. We collect feedback from real-world usage and incorporate new data patterns to enhance detection accuracy. This iterative process ensures our AI detection remains at the forefront of technology, adapting to new language models and writing styles as they emerge.\n\nTo maintain the highest level of accuracy, we consistently retrain our AI detector models with updated datasets that include the latest AI-generated content. This regular retraining process ensures our detection capabilities stay current with evolving AI technologies and can reliably identify content from the newest language models.\n\nOur classifier uses a traditional language model architecture.
