What you get

One zip. Everything to own it.

Personal Operating System gives builders a calm owned workspace they can shape into a private productivity product. The foundation ships with clear data boundaries, seed workflows, agent instructions, and deploy-ready Next.js structure so an AI coding agent can safely add the exact routines, views, and review cycles you want.

  • Today view with focused planning primitives
  • Projects, tasks, notes, routines, and reviews
  • Clear storage adapter boundaries
  • Responsive mobile-first workspace
  • Seed data and customization recipes
