Pangram Labs

Pangram Labs is an AI content detection platform with the strongest published accuracy claims in the category — 99.98% accuracy distinguishing human-authored from AI-generated text, with sentence-level highlighting that identifies AI-assisted edits and partial AI generation within otherwise human documents. The product covers AI Segment Analysis (quantifies AI portions inside documents), AI Assistance Detection (highlights AI-edited passages), an integrated plagiarism checker, a Chrome Extension and Google Docs integration for real-time browsing-time detection, batch processing of up to 100 files (PDF, DOCX, RTF), multilingual detection across 20+ languages, and LMS integrations (Canvas, Google Classroom, Moodle, Brightspace). Independent University of Chicago research puts Pangram's false-positive rate at 0.5% on product reviews vs GPTZero 2.4% and Originality.ai 1.7%. Used by Canvas, Quora, ChatPDF, Newsguard, Wiki Education, LessWrong, and Tremau. Pangram positions against Originality.ai (incumbent in the SEO content niche), GPTZero (academic-first), Copyleaks (enterprise plagiarism + AI detection), Turnitin (academic incumbent), and Winston AI (similar positioning).
