Built a Local AI Agent That Controls My Phone — Completely Free, Completely Private

I spent the last few weeks building an AI agent that controls my Android phone from my laptop.

What it does:

• Send WhatsApp messages: "Tell Mum I'm on my way"
• Search YouTube: "Find videos about AI agents"
• Take photos, write notes, open any app
• Multi-step: "Open YouTube and search for AI, then save to notes"
• Voice control with wake word

How it works:

• Multi-agent system (Researcher, Router, Planner, Judge, Teacher)
• Reads phone screen in real-time
• Knowledge graph for relationships ("message my brother" → finds correct contact)
• Self-learning from every action
• Safety approval levels

Tech stack: Python, ADB, Ollama, Whisper, Piper, NetworkX, SQLite

Everything runs locally. No cloud. No tokens. No data leaves the device.

Happy to answer questions about the architecture or implementation.
