Pangram – AI Content Detector

Pangram is a professional-grade AI content detector built for educators, publishers, and enterprises where false accusations carry real consequences. Unlike GPTZero, which leans on perplexity and burstiness, Pangram uses a “synthetic mirror” training method validated by University of Chicago and University of Maryland researchers.

Key Features

The platform claims 99.98% detection accuracy with a 1-in-10,000 false positive rate—the lowest verified in the category as of 2026. It identifies output from GPT-4, GPT-5, Claude, Gemini, Grok, Llama, and DeepSeek, and maintains 97% accuracy on QuillBot-humanized text where competitors drop to 40–60%. Multilingual support spans 20+ languages including Arabic, Japanese, Hindi, and Korean. A Chrome extension, Google Docs add-on, and LMS integrations for Canvas, Moodle, and Google Classroom let teams scan inside existing workflows. Plagiarism detection ships on every paid scan.

Use Cases

University professors verify student essay submissions without the false-positive risk that gets innocent writers flagged. Editorial directors at publishing houses screen freelance submissions before contracts move forward. Trust and safety teams at platforms moderate AI-generated spam at scale through the API. HR recruiters validate that candidate writing samples and cover letters reflect actual ability rather than ChatGPT output.
