AI Detector by OnlineUtility

OnlineUtility's AI Content Detector is a lightweight, utility-driven tool designed for the immediate identification of text generated by Large Language Models (LLMs) including GPT-4o, Claude 3.5, and Gemini. As of 2026, it maintains a significant market niche as a 'first-pass' diagnostic tool due to its no-login, zero-friction architecture. The tool evaluates text based on linguistic predictability, specifically focusing on perplexity and burstiness metrics to determine machine-generated patterns. While it lacks the deep recursive analysis of paid enterprise platforms, its speed and accessibility make it a staple for SEO professionals, editors, and educators who require non-intrusive verification. Technically, the platform operates as a client-side wrapper that interfaces with pattern-recognition algorithms to deliver a probability score. Its position in the 2026 landscape is defined by its commitment to the 'Open Utility' model, providing a necessary counter-balance to increasingly expensive, subscription-based detection services. It is best utilized as a screening layer before more intensive manual or paid-audit processes are initiated, offering a high-level confidence interval for general content authenticity.
