RedPlanetHQ/core is a personal AI operating system built with a modern TypeScript/Node.js stack using Remix as the web framework, Prisma as the ORM, and Neo4j for graph-based knowledge management. The system appears to function as a central hub orchestrating AI capabilities for personal use, with a ‘butler’ concept suggesting agent-like task automation and assistance. Redis is used for caching and real-time operations alongside PostgreSQL for data persistence.
