Pangram Labs

Pangram Labs is a company that provides an AI detection platform designed to identify AI-generated text with high accuracy. The platform analyzes writing for patterns common in content produced by large language models such as ChatGPT, Gemini, Grok, Llama, and Claude, using natural language processing and a large dataset of human and AI writing. Pangram claims a detection accuracy of 99.98% or higher, a figure that it states has been verified by third-party researchers from institutions including the University of Maryland and the University of Chicago. The service is aimed at universities, schools, and enterprises that need to maintain content transparency in academic, media, and business contexts.

In addition to its core AI detector, Pangram offers a browser extension (including a Firefox extension), API integrations, and LMS integrations, as well as a plagiarism checker and multilingual AI detection capabilities. The platform is designed to be used by educators, journalists, and organizations that need to distinguish between human and machine-authored text. Pangram also operates a separate affiliate-driven directory called aitools.fyi, which is a curated search engine for discovering AI tools, but the primary product described on the company website is the AI detection service.

Pangram appears to offer free checks, though the exact limits of the free tier should be verified. The pricing model is listed as "contact" for sales, indicating that custom or enterprise pricing is available. The tool is SaaS-based and requires internet access to function.
