A Systematic Analysis of Linguistic Features in AI-Generated Text Detection Across Domains and Models

In three linesLarge-scale empirical study of 284 linguistic features across 27 LLMs and 10 text domains for detecting AI-generated text. Classifiers based on linguistic features reliably distinguish AI from human text. Lexical richness remains robust across model families and domains, while other indicators prove strongly context-dependent.
