AI Detector by SpellCheckTool
Verify content authenticity with advanced linguistic pattern recognition and deep-scan AI analysis.
Enterprise-grade AI detection integrated with industry-leading plagiarism verification for academic and professional integrity.
The AI Content Detector by PlagScan (now a part of the Turnitin ecosystem) represents a sophisticated 2026-market-ready evolution in linguistic forensics. Unlike basic keyword-matching tools, this system utilizes a multi-layered Transformer-based architecture to evaluate text for the statistical signatures of Large Language Models (LLMs) including GPT-4o, Claude 3.5, and Gemini 1.5 Pro. The technical backbone combines perplexity analysis—measuring the unpredictability of word choices—with burstiness evaluation, which assesses the structural variety typical of human writing. As of 2026, the tool has been refined to distinguish between human-edited AI content and pure machine generation, offering a 'human-AI hybrid' probability score. It is deeply integrated into the PlagScan/Ouriginal infrastructure, providing a unified report that cross-references plagiarism and AI usage. This dual-engine approach makes it a critical component for educational institutions and publishing houses that require high-precision verification. The platform supports multiple document formats and provides an API-first architecture for seamless LMS (Learning Management System) integration, ensuring that content integrity is maintained at scale across global digital workflows.
