Private Viewer: Ai + Sandbox

Privacy by Architecture No accounts to create. No analytics running in the background. No cloud sync unless you choose it. Your files stay on your device — iOS sandbox or macOS app container — period. Offline Rendering Engine Renders React, JSX, TypeScript, HTML, and CSS without a build server. Babel transpiles at runtime. CDN scripts are cached locally for airplane-mode development. Code Editor + Versioning Native editor with syntax highlighting and auto-completion. Git-style save points let you snapshot, diff, and restore — no git required. 3D Model Viewer Open .usdz, .glb, .gltf, .obj, and .dae files natively on iOS. Rotate, zoom, inspect — no third-party app needed. Persistent Remote Sessions Magnum Brain Tuning tier includes tmux-backed SSH sessions to your Mac orchestrator. Sessions survive network disconnects, sleep, and app restarts. Send a task from your phone and get notified when it's done.
