PlanMode is officially in beta. You just start chatting with the agent and it will automatically switch to PlanMode and plan whatever you want to build. After approval, it auto-creates tasks for it to follow.

We believe the future of software development isn't about faster processors or larger monitors. It's about access. It's about removing the friction between "I have an idea" and "I have shipped code."

Your IDE just went mobile. Spin up AI agents in traffic. Arrive at your desk and resume exactly where you left off—100% synced repos, sessions, and state. Stop context switching. Start orchestrating. The persistent dev environment is here.
