Building Persistent AI Systems Without a Traditional Database

This paper shows a new way to build AI assistants without using a complex database. Instead of hiding data in a database, we store the AI’s memory, personality, and skills in simple Markdown files that anyone can read. For systems like personal assistants or those with fewer users, a heavy database is often overkill. working_memory.md episodic_memory.md semantic_memory.md personality.md habits.md self_reflection.md skills.md skill_context.md To help the AI find information quickly, we use a tool called FAISS to search through these files, but the files themselves always remain the main source of truth. By using simple files instead of a database, the system is much easier to fix, track, and move. It’s a perfect 'middle ground' for personal AI projects because it’s simple to manage but still powerful enough to handle complex tasks.
