Core technology

Engineered for absolute precision

Unlike rule-based detectors, GPTZeroPro uses deep learning ensembles to analyse semantic variance, structural bursts, and token probability distributions.

Multi-layered detection architecture

Combines linguistic pattern analysis with statistical perplexity scoring to identify AI signatures with 99% accuracy.

Trained on billions of tokens

Proprietary models continuously updated on the latest outputs from ChatGPT, GPT-4, Claude 3.5, and Gemini 2.0.

Real-time inference engine

Optimized backend delivers comprehensive full-document analysis in milliseconds.

Enterprise-grade privacy

Your data is never used to train external models. Strict SOC2-compliant data handling.
