AI Content Detector by TextGen

The AI Content Detector by TextGen is a sophisticated forensic tool engineered for the 2026 digital landscape, where the distinction between human and synthetic text has become increasingly blurred. Utilizing a multi-layered detection architecture, it moves beyond simple perplexity and burstiness metrics to include semantic entropy analysis and transformer-specific fingerprinting. The engine is trained on a massive corpus containing outputs from GPT-4o, Gemini 1.5 Pro, Claude 3.5 Sonnet, and Llama 3, allowing it to identify the distinct mathematical signatures of various LLMs. Its 2026 market position is solidified by its focus on 'ghostwriting' detection—identifying cases where AI has been used to heavily edit human text. The tool provides a granular, sentence-level heatmap that differentiates between purely synthetic text, human-written content, and AI-assisted transitions. Designed for enterprise-scale operations, it offers high-throughput API endpoints and seamless integration into CMS workflows, ensuring that publishing houses, academic institutions, and legal firms can maintain content provenance in an era of automated misinformation.
