M.A.R.K. (Modular Artificial Reasoning Kernel) is a futuristic autonomous AI dashboard and cognitive orchestrator with a British female AI persona who addresses the user as "Sir" or "Mr. Lobley". The system features voice interaction using the Web Speech API with support for over 30 languages, an AR camera HUD with real-time object detection powered by TensorFlow.js COCO-SSD model, persistent long-term memory stored via IndexedDB for client-side conversation persistence, a 3D Earth globe for navigation built with Three.js, sonar radar with 360-degree sweeping animation, a confidence threshold monitoring ring displaying system certainty at approximately 96.7 percent, and an emergency system break control that instantly freezes all automation. The application is fully client-side and runs entirely in the browser with no backend required. It supports Web Bluetooth for device connectivity and the Geolocation API for navigation features. The modular architecture separates perception, reasoning, memory, and action into independent swappable components, each communicating through well-defined interfaces. A double-clap wake detection system using the Web Audio API allows hands-free activation. The British female text-to-speech voice is generated via the SpeechSynthesis API with en-GB locale selection.
