About AIDetector.pro
AIDetector.pro is a sophisticated linguistic analysis platform engineered to distinguish between human-authored text and content generated by Large Language Models (LLMs) including GPT-4o, Claude 3.5, and Gemini Ultra. By 2026, the platform has evolved its technical architecture to move beyond simple perplexity and burstiness metrics, utilizing a proprietary 'Forensic Semantic Mapping' engine. This engine analyzes syntax patterns, n-gram distribution, and semantic entropy to identify the subtle watermarks left by transformer-based models. Positioned as a mission-critical tool for publishers, educators, and SEO agencies, it provides a dual-utility workflow: first, identifying AI-generated segments with a high-resolution heatmap, and second, providing a 'Humanizer' tool that suggests stylistic rewrites to improve human-sounding metrics. The 2026 iteration features enhanced detection for recursive AI editing and multi-step prompting techniques, making it one of the few tools capable of identifying content that has been passed through multiple 'stealth' rewriters. Its infrastructure is built for high-throughput enterprise environments, offering low-latency API endpoints and a robust security posture for high-volume content auditing.
