Personal AI infrastructure, built in the open.
I'm David Chang. I build the plumbing that turns an AI assistant into a chief of staff — hosted memory, a portable second brain, and the MCP servers that wire it all together.

Nexus
coming soonOne-brain platform: hosted memory + command center.
Nexus gives your AI assistants a single persistent brain — memory that survives every session, shared across every surface you work in, with a command center to see and steer what it knows.
- Hosted memory that persists across sessions, tools, and devices
- One command center for everything your assistant knows and does
- Built on the same MCP wiring published below
