Features

• Code Generator — pick a robot, pick an intent (beep, probe, drive, wave), get Pybricks or LEGO Stock Python in one click. Download as .lms file ready to load in the LEGO app.
• Builder Session — human-in-the-loop debug loop: propose one safe test, record what happened, get the next suggestion.
• Connect — Bluetooth (BLE, recommended) or USB Web Serial. Stock LEGO firmware supported via LWP3; full REPL with Pybricks.
• Voice KWS — load an Edge Impulse WebAssembly keyword-spotting model and control the robot by voice.
• MCP Server — 14 tools for AI agents (Claude Desktop, VS Code Copilot, Cursor). Zero runtime dependencies.
