Seeking Advice on Modular Personal AI Assistant Architecture
Sharp_Control4582 · reddit · 2026-07-19
The author is building a personal AI assistant named Lyra and is seeking advice on software architecture and AI systems.
The design goal isn't a simple chatbot, but a long-term evolvable personal software ecosystem:
- User → Interface → Personality → Memory → Skills → Tools → Projects
- The core system handles communication and decision flows
- The AI layer can connect to different models/providers
- Memory is divided into three layers: short-term, important, and core
- The skill/plugin system is designed for independent expansion (e.g., study assistant, scheduling, reminders, file management, coding assistant, research tools)
The author primarily wants to know:
- What architectural pitfalls to avoid
- How to design long-term memory
- How to build a scalable skill/plugin system
- What challenges arise when scaling from a prototype to a larger application
