## AI writing has detectable patterns
AI-generated text contains structural, stylistic, and semantic patterns that can be identified by trained software. Detection is not magic, it actually works.

> AI detection is not magic. It can actually work.
## Pangram uses advanced detection
Pangram analyzes text using natural language processing and massive datasets of human and AI writing from models like ChatGPT, Gemini, Grok, Llama, and Claude.
## Third-party verified accuracy
Researchers at the University of Chicago and University of Maryland have independently verified Pangram's accuracy, confirming it leads the industry.
## Content transparency matters now
As AI-generated content spreads through academia, media, and business, distinguishing human from machine text builds trust between students and teachers and maintains journalism integrity.
## Detects 26 AI models
Pangram benchmarks against 26 frontier models including GPT-5.6, Claude Opus 5, Gemini 3, and Grok 4.3, with accuracy ranging from 99.4% to 99.9%.
## Combines AI and plagiarism checks
Pangram detects both AI-generated content and plagiarism in one tool, plus identifies AI-assisted edits and analyzes what percentage of text is AI-written.
## Proprietary technology, not borrowed
Pangram uses proprietary technology developed over years of research, not open-source models. It relies on diverse datasets and hard negative mining for industry-leading false positive rates.
## Outperforms trained humans
Independent studies show Pangram's AI detection outperforms trained human readers at identifying AI-generated content.
## Catches humanized AI text
Pangram detects AI-generated text even after it has been processed by tools designed to evade detection, ensuring reliable identification.
## Works in 20 plus languages
Pangram's AI detection works across more than 20 languages including English, Arabic, Chinese, French, German, Japanese, Spanish, and many others.
## Founded by AI researchers
Pangram was founded in Brooklyn in 2023 by AI researchers from Tesla and Google with a mission to rebuild trust amid rising generative AI content.
## Four-step detection process
Users paste or upload text, Pangram scans for AI content, displays detailed results with highlighted sections, and stores records for future access.
## Integrates everywhere you work
Pangram works with Chrome, Google Docs, Canvas, Google Classroom, Moodle, and Brightspace, making it easy to use across multiple platforms.
## Lowest false positive rate
Pangram's false positive rate is 1 in 10,000, compared to competitors like GPTZero at 2.4% and Originality.ai at 1.7% on product reviews.
## Teachers trust the results
Pangram's documented low false-positive rate allows educators to treat AI flags as invitations to talk, never as presumptions of guilt.

## Trained on 1 million documents
Pangram's classifier was initially trained on approximately 1 million diverse documents of human-written text and AI-generated content from frontier models.
## Continuously improves detection
Pangram undergoes iterative refinement using real-world feedback and consistently retrains models with latest AI-generated content to stay current.
## Free plan with 20 daily checks
Pangram offers 20 free checks per day after signup, including AI assistance detection. Subscriptions unlock additional credits and plagiarism detection.
## Your data stays private
All user data is encrypted and stored securely. Pangram never shares or sells data to third parties.
## Key takeaway

Pangram detects AI-generated content across 26 major language models with a false positive rate of just 1 in 10,000, making it reliable enough for high-stakes academic and professional settings.
