About Pangram Labs
Pangram Labs is an AI detector that identifies AI-generated text with 99.98% accuracy, independently verified by researchers at the University of Chicago and University of Maryland. Built by AI researchers from Google and Tesla, it analyzes patterns in writing from all major LLMs, including ChatGPT, Gemini, Grok, Llama, and Claude, using proprietary technology rather than simple perplexity scoring. Unlike basic detectors that give a single score, Pangram provides AI Segment Analysis to highlight exactly which parts are AI-generated, and AI Assistance Detection to flag segments edited by AI rather than fully generated. It also includes a built-in plagiarism checker, so you can check for both AI and plagiarism in one place. The tool supports over 20 languages and can detect humanized or evaded text. Pangram integrates into your existing workflow via Chrome and Firefox extensions, Google Docs, and LMS platforms like Canvas, Moodle, and Google Classroom. The free plan offers 4 scans per day, while paid tiers add more scans and plagiarism checks. The latest Pangram 4 model is now available, and a new Image Detection feature lets you upload images to check for AI generation. Trusted by universities, schools, and enterprises worldwide, Pangram is positioned as a comprehensive authenticity tool for educators, publishers, and HR teams who need defensible, third-party-validated results.
Behind the Verdict
Pangram stands out in the crowded AI detector market by prioritizing accuracy and transparency. The 99.98% accuracy claim is backed by third-party researchers at the University of Chicago and University of Maryland, which is rare among competitors. The tool's AI Segment Analysis and AI Assistance Detection features go beyond a simple probability score, which is valuable for educators who need to pinpoint specific AI-written paragraphs. Strengths: The free tier allows 4 scans per day, making it accessible for occasional checks. The plagiarism checker is a nice addition for a combined authenticity check. Multilingual support (20+ languages) is a plus for global institutions. The Chrome and Firefox extensions and Google Docs integration smooth workflow integration. The latest Pangram 4 model and Image Detection preview show continued innovation. Weaknesses: The credit system can be confusing and costly for heavy users — documents over 1000 words consume multiple credits. Plagiarism detection is not available on the free plan, so you need to pay. The API pricing is per credit, which might be expensive for bulk scanning. The tool is not suitable for real-time detection (e.g., live chat). Where it fits: Best for educators, universities, publishers, and HR teams that require high accuracy and defensible results. For enterprises with large volumes, the Team or Enterprise plans offer needed admin controls and API access. Where it doesn't: Individuals needing unlimited free scans or quick one-off checks without plagiarism features; organizations needing on-premise deployment.
