Overview

Pangram Labs builds an AI content detection platform that determines whether text was written by a human, AI, or a mix. The system analyzes content through machine learning models trained on millions of samples, and specializes in spotting AI-generated text even after paraphrasing or passing through a “humanizer.” It can identify outputs from models like GPT-4, Claude, and Gemini and highlights the exact passages with a sentence-level confidence histogram. It is accessible via a web dashboard, a Chrome extension, and an API for integration into other systems such as learning management systems. Pangram Labs serves education, business, and media groups, with a subscription-based model for individuals and enterprises. Its goal is to help educators, publishers, and organizations verify content authenticity and maintain academic integrity and policy compliance.
