Pangram develops machine learning models to detect AI-generated and AI-assisted text and images, training on tens of millions of human documents and synthetic mirrors to learn stylistic differences. The company recently launched Pangram 4, its next-generation text detector which it says is over 99% accurate, and Pangram Image, an image detector currently available in research preview. Pangram provides a $20/month web subscription, a Chrome extension that labels content in real time across platforms like X, LinkedIn, Substack, Reddit, and Medium, and an API used by customers such as Substack, Quora, schools, publishers, and recruiters. Founders Max Spero and Bradley Emi, both Stanford AI and machine learning graduates, started the company about two years ago in response to the proliferation of AI-generated content following ChatGPT. The team reports a very low false-positive rate (roughly one in 10,000 human documents flagged) and highlights use cases ranging from publisher integrations to academic and moderation settings. The company has not disclosed revenue figures or detailed financial metrics in the article.
