Proven the most reliable and accurate AI detector on the market by third party researchers , including the University of Maryland and the University of Chicago.
What is an AI detector and should you use one?
AI 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.
Pangram'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. Pangram's accuracy leads the industry and has been verified by researchers at the University of Chicago and University of Maryland.
In 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.

Does Pangram detect the latest AI models?
Yes. Pangram is trained specifically to detect the latest AI models from frontier labs like OpenAI, Anthropic, Google, Meta, DeepSeek, xAI, and more. We benchmark against 26 models (so far) and they are available to see on our model card . We're accurate on 99.7% of these AI-generated samples. We test broadly on every Pangram release and retest on every major model release.
Anthropic Claude Opus 5 99.8% accuracy Tested Jul 2026
OpenAI GPT 5.6 99.6% accuracy Tested Jul 2026
Google Gemini 3 99.5% accuracy Tested Nov 2025
xAI Grok 4.3 99.4% accuracy Benchmarked Jul 2026
Detect AI and plagiarism
Pangram 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. Pangram also detects AI-generated images .
AI Segment Analysis
Pangram won't just tell you how confident it is that the document is AI, but also how much of it is.
AI Assistance
Pangram will highlight segments that have been edited by AI rather than fully AI-generated.
Plagiarism Checker
Check for plagiarism and AI all at once. Perform an AI plagiarism check with one click.
How is Pangram's AI detector different?
There 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.
Years of research
Uses proprietary technology with years of research and development behind it, not an open source model or commercial LLMs covered with branding.
Trained on diverse data sets
Pangram 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.
Detects all LLMs
Pangram can detect content from all major language models including ChatGPT, Claude, Gemini, Llama and more, making it a comprehensive solution for AI detection.
Supports 20+ languages
Our AI detection works across more than 20 languages, making it a truly global, multilingual solution for institutions and businesses worldwide.
Out-performed trained humans
Independent studies have shown that Pangram's AI detection outperforms trained human readers in identifying AI-generated content.
Detects humanized text
Pangram can detect AI-generated text even after it has been "humanized," or processed by tools that attempt to evade AI detection, ensuring reliable detection.
Verified accuracy
Our accuracy and reliability have been independently verified by third-party researchers and educational institutions.

Users love Pangram
Pangram is pretty incredible. 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.
University of Chicago Booth School of Business
For 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.
— Susan Ray, Associate Professor Of English, Delaware County Community College
There'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.
We compare human experts with five AI detectors, including Pangram and GPTZero. Among automatic detectors, Pangram significantly outperforms the rest.
Pangram is really one of the best AI detectors we have, and y'all should use it.
Based on our experiences in the fall term, we have high confidence in Pangram as a detector of AI content in Wikipedia articles.
— LiAnna Davis, Chief Programs Officer and Deputy Director at Wiki Education
Pangram 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.
The 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

Our 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.
After 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.
To 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.
