What is rho?
rho is an AI agent that keeps running on the user's own devices (phone, laptop, server) and remembers what it has learned and the user's preferences even when sessions change. With the heartbeat feature, it reads a checklist at set intervals and runs scheduled tasks. On Android, it works with Tasker to read the screen, press buttons, and open apps. Data stays on the device, and you sign in with an existing Claude Pro, ChatGPT Plus, or Gemini subscription. You can control it through the terminal, web UI, Telegram, or agent email.
- Memory that persists across sessions (organized daily)
- Periodic autonomous check-ins (heartbeat, default 30 minutes)
- Device control through Android Tasker integration
- View, search, and edit learned memory
- TypeScript extensions loaded at runtime
- Local-first storage, uses the user's own LLM provider
- Control through terminal, web UI, Telegram, and agent email
Who uses rho and for what
