Mosaic
Defining the frontier of multiplayer AI.
Mosaic gives teams and their coding agents shared memory across every session, so everyone can understand what happened, why decisions were made, and pick up where someone else left off. We started as a real-time coding environment where multiple people and their agents can work together live. It went viral, defined the multiplayer AI category, and inspired frontier labs like Anthropic. Together, we’re building the infrastructure for people and agents to share context and work together.
