Overview

Pangram Labs is an AI content detection platform designed to identify AI-generated text with what the company claims is 99.98% accuracy. Built by former Tesla and Google engineers, it uses proprietary detection models to analyze text and determine whether it was written by a human or generated by AI tools like ChatGPT, Claude, or Gemini.

The platform integrates directly into learning management systems (Canvas, Brightspace, Moodle, Google Classroom) and Google Docs, making it particularly useful for educators checking student work. Its detection engine has been independently evaluated by researchers at the University of Chicago and University of Maryland, achieving near-perfect accuracy scores across multiple AI models.

Pangram Labs is best suited for educators, publishers, and content teams who need reliable AI detection at scale. Its LMS integrations make it especially strong in academic settings, while API access serves publishers and platforms needing automated content verification.
