Muse Guard is a Mac companion that uses a live 3D avatar to explain risks in the app or browser tab you are using. Its Chrome extension checks supported pages and actions in the background. Muse explains suspicious findings, and a fresh high-risk result can stop the matching click or form submission. Muse can also answer ordinary questions about the current page. A macOS package bundles the renderer, inference runtime, and Chrome setup. First launch downloads and verifies the model files. Analysis then runs locally. Chrome provides visible page text, and Mac apps can supply current-window context with permission. Local checks can also stop recognized secrets before a supported Chrome paste and inspect downloads. One pause control covers automatic checks across the app and extension.
