Julian introduces a focused, modern model for open-source personal agents. Running entirely on Claude Code through an Anthropic subscription, he serves as a single coordinating presence who helps users summon, train, and collaborate with eight specialized agents built in Agent Team mode. Beyond orchestration, Julian experiments with a new, more intentional affective relationship between humans and their agents. He operates inside a secure virtual machine with minimal persistent storage; transcripts, files, and skills live instead in a CRDT database, enabling seamless, real-time sync across phones, laptops, and desktops. Julian isn’t meant to do everything. But he makes simpler, cleaner, and more human.
