What is Pangram?
Pangram is an AI detection tool that analyzes text, and also images, to estimate whether content was written or created by AI. It is built on natural language processing and a large dataset of human and AI writing, and the company says it has been verified by researchers at the University of Chicago and the University of Maryland. The site lists benchmark accuracy against many models, including Claude, GPT, Gemini, Grok, DeepSeek and Llama.
You upload a file or paste text, and Pangram reports how confident it is that the document is AI-generated and how much of it is. It can also highlight segments that were edited by AI rather than fully generated, and it includes a plagiarism check that runs alongside the AI scan. Image detection allows a limited number of free scans per day. Integrations mentioned include a browser extension, Gmail, Google Docs and an API.
