Our Proprietary Detection Technology

AI DETect combines multiple state-of-the-art detection methods into a single unified engine β€” delivering accuracy that no single method can achieve alone.

01

Perplexity & Burstiness Analysis

Measures how predictable the text is token-by-token. AI-generated text exhibits lower perplexity (more predictable) and lower burstiness (more uniform sentence complexity) than human writing.

02

Compression-Ratio Detection

Based on research from Thinkst (ZipPy method) β€” AI text compresses more efficiently against known AI corpora due to shared token patterns, providing a fast statistical baseline.

03

Deep Learning Classification

Our BERT-based classifier trained on millions of human and AI text samples provides fine-grained segment-level analysis, detecting even partial AI assistance within longer documents.

04

Multi-Provider AI Analysis

We cross-validate results through multiple AI systems with automatic failover β€” ensuring consistent availability and accuracy even under heavy load.
