It is a desktop agent that helps user like every other agents such as claude code or codex.
But while it does that, it will also maintain the local folder as its long-running projects, recording down the current state, every decision made, lessons learnt and artifacts produced.
Within the local project, agent's work compounds, every tasks start on top of the previous work.
It also supports dispatching cli agents like codex and claude code, so that you don't need to explain the project to them ever again.
That's what we mean by a "project agent" — an agent over your project, not over your session.
