Describe an app once. OpenDaemon's AI Developer writes a plan of phases plus a checklist, routes each phase to the agent inside your Claude or Codex desktop app or Antigravity IDE (not a CLI), reviews every report and screenshot, and sends the work back until the app runs. The same free Windows hub runs a Playground AI society on your PC and an assistant you can reach from Telegram, WhatsApp or Slack. Free NVIDIA models out of the box, or bring your own key.
