Pluto is a natural language AI system that runs directly on microcontrollers with minimal memory footprint (0.5 MB RAM), enabling users to control hardware through voice commands instead of traditional programming. It supports multiple platforms including Arduino, ESP32, and STM32, and can manage GPIO, PWM, I²C, SPI, UART, and sensor operations without requiring cloud connectivity. The proprietary C++ framework is distributed as pre-configured hardware rather than public software.
