Pangram – AI Detection that works

"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."

"The Anthropic release has finally allowed me to test Pangram on whether it'd be able to detect the AI writing of a 'fresh model' that it likely hasn't been tuned on. It succeeds with 100% accuracy on the three writing samples I tried."

"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."

"Instead of detection being an additional layer I have to negotiate, Pangram is straightforward and makes verifying student work smooth."

"Pangram is really one of the best AI detectors we have, and y'all should use it."

"My students are so convinced of its accuracy that it seems to be an even greater deterrent than anything else. It is a great tool for a teacher to have in their arsenal."

"pangram labs is so good at AI detection. it doesnt just catch the "its not x, its y" type llm-speak but even if you had chatgpt speak like @shauseth it can detect it! so in context learning is also easy to detect! insane sorcery by @max_spero_ and team "

AI content detection, like Pangram's AI checker tool, analyzes text for traces of AI writing. AI detectors return a prediction and a score based on the likelihood that the text is AI-generated.

Pangram's false positive rate (the rate at which human documents are incorrectly flagged as AI) is currently 1 in 10,000. This number is calculated on an aggregate of public datasets containing tens of millions of written documents.

Yes, all user data is encrypted and stored securely on our servers to be displayed in your history. We never share or sell your data to any third parties.

Pangram detects AI writing from ChatGPT, GPT-4o, GPT-4.5, Claude Sonnet by Anthropic, Google Gemini, Deepseek, Meta AI, Grok, Llama, Mistral, OpenAI's o1, o3, Perplexity and Deep Research. Pangram also detects AI suggestions from AI writing tools like Grammarly and Quillbot. Pangram even detects new and unreleased AI models.

Pangram uses writing style, word choice, syntax choice, and grammatical structure to detect AI writing. Our AI writing detector only looks at the content of the text submitted. It does not compare the text to other submissions in a database or on the web like traditional plagiarism checkers, and it does not capture writing process data such as cut-and-paste. Pangram does not access OpenAI's database or analyze a user's browsing history.

Professors use Pangram to set boundaries on AI use and ensure that students properly learn the material by using our AI and plagiarism detectors directly in their LMS. Academic integrity departments use Pangram to provide evidence for cases that goes beyond the score - highlighting the most common phrases that LLMs use and comparing submissions to actual AI-generated responses.

Many other AI detectors don't keep up-to-date with the latest AI models. Pangram is constantly collecting writing samples from the latest and most capable AI models to ensure that the software can detect writing from all AI services, even those from unreleased models or AI editing tools.
