Detect AI-generated content with unmatched accuracy.
Grade: A — Score: 85/100
Pangram utilizes advanced natural language processing and a vast dataset of human and AI writing to effectively analyze and detect patterns in AI-generated content from popular models like ChatGPT and Claude. Its proprietary technology has been developed through years of research, ensuring it outperforms other detection tools in the market.
The workflow is streamlined for users: simply input text or upload files, and Pangram's algorithms will scan for AI content, providing detailed results that highlight AI-generated segments and offer comprehensive analysis. This process is designed to be user-friendly, integrating seamlessly with platforms like Google Docs and various learning management systems.
In an era where AI-generated content is prevalent, the risks of misinformation and lack of transparency are significant. Pangram addresses these concerns by providing reliable detection that fosters trust in educational and professional settings, ensuring that users can distinguish between human and machine-authored text.

Consider switching to Turnitin: Turnitin is widely recognized in academic settings for plagiarism detection.
Pangram differentiates on false positive rate — its independently verified rate of 1 in 10,000 is the lowest among commercial AI detectors, compared to GPTZero's under 1% and Turnitin's higher documented rates that have led institutions like Vanderbilt to disable it. The University of Chicago Becker Friedman Institute found Pangram achieved essentially zero false positive rates on medium-to-long passages, calling it 'the only AI detector maintaining policy-grade levels on our main metrics.' GPTZero offers stronger recall on hybrid/mixed documents and broader ESL-fairness testing, while Turnitin's advantage is deep institutional LMS integration and established plagiarism checking. Pangram supports 20+ languages versus GPTZero's more limited multilingual coverage.
Pangram claims 99.98% accuracy, independently verified by researchers at the University of Chicago and the University of Maryland. The University of Maryland study found that Pangram outperformed both trained human readers and all other commercial AI detectors tested, including GPTZero. Pangram's proprietary EditLens architecture analyzes structural, semantic, and syntactical patterns rather than relying on perplexity and burstiness metrics, which are known to produce false positives on formal human writing such as legal documents and academic abstracts.
Yes. Pangram detects AI-generated text even after it has been processed by humanizer tools or paraphrasing services designed to evade detection. The Pangram 3.2 model (released February 2026) specifically added increased accuracy against the latest humanizer outputs. Independent benchmarking on the RAID dataset found that Pangram and Originality.ai were the only two tools that effectively neutralized paraphrasing-based evasion, while perplexity-based detectors like GPTZero and Turnitin were more vulnerable to these techniques.
Pangram integrates directly into Canvas, Google Classroom, Moodle, and BrightSpace learning management systems. The Educational Institution license provides unlimited AI checks and plagiarism checks within the LMS, automatic detection of copy-paste plagiarism and reused submissions from past years, and dashboards showing usage trends and AI-use statistics. Students see the same report as teachers within the LMS shell. Institutional licensing requires contacting Pangram's sales team for custom pricing.
No. Pangram explicitly states that user submissions are not used to train, develop, refine, or improve their AI detection models or any machine learning systems. Their privacy policy confirms data is not shared with third parties, not used for marketing, and not used to build new products. The detection model is trained on a separate proprietary dataset of approximately 1 million documents composed of publicly licensed human-written text and AI-generated text from frontier LLMs. Pangram holds SOC 2 Type II certification (verified by AssuranceLab), and content is deleted within 30 days of account closure.
Pangram's multilingual AI detection works across more than 20 languages including English, Arabic, Chinese, Czech, Dutch, French, German, Greek, Hindi, Hungarian, Italian, Japanese, Korean, Persian, Polish, Portuguese, Romanian, Russian, Spanish, Swedish, Turkish, Ukrainian, Urdu, and Vietnamese. The same detection engine handles all supported languages without requiring the user to specify the input language. Detection accuracy is strongest in English, with some reviewers noting reduced performance in languages like Hindi and Mandarin.
Introduced with Pangram 3.0, AI assistance detection classifies text into granular categories: fully human-written, light AI assistance (surface-level changes like grammar fixes and phrasing updates), moderate AI assistance (AI rewrote significant portions or added its own content), and fully AI-generated. The system uses segment analysis with an Adaptive Boundaries algorithm that divides documents into overlapping windows, producing a color-coded visual overlay showing which specific sentences appear AI-generated versus human-written, with granularity down to approximately 75 words. AI assistance detection is included for all subscribers and available as a limited trial for free users.
Yes. The Pangram API accepts raw text via secure HTTPS POST requests and returns structured JSON with a prediction score and confidence level for instant, real-time content scoring. Developer API credits are sold in packs starting at $25 for 500 credits, with each credit covering 1,000 words ($0.05 per 1,000 words). Larger packs are available up to $1,000, with auto-refill options. API credits are separate from dashboard subscriptions — they cannot be used in the web dashboard. Research credits are available for academic researchers on request. Enterprise customers receive progressive volume discounts beyond the developer tier.
