Mosaic is a Meta-powered AI agent ecosystem that turns natural-language requests into coordinated actions across Windows apps, the browser, and Android. Everyday workflows are fragmented across devices. Research happens in browser tabs, files live on a computer, and other tasks require phone apps. Users must manually move information and repeat steps between them. Mosaic brings these environments together. Mosaic Desk 3 operates Windows applications using screenshots and accessibility trees. Spark Pilot 3 handles websites through a Chrome/Edge extension. Mosaic Phone uses Android Accessibility to understand and interact with phone apps. When a task needs another environment, the initiating agent delegates that step, waits for a concrete report, and continues the original workflow. A local native bridge connects desktop and browser, while an encrypted relay connects the PC and phone over the internet. Mosaic includes app approval prompts, stop controls, progress reporting, and encrypted cross-device task messages. Its goal is to reduce repetitive work and make multi-device workflows accessible through a single request.
