This tutorial walks through building a persistent memory architecture on top of Claude. The setup combines three layers: Claude's native memory with regular cleanup routines, a local Context File System that stores structured knowledge files Claude can reference, and an Obsidian-based second brain that links and evolves information over time. The result is a workflow where Claude retains context across sessions, surfaces relevant past knowledge, and improves its outputs without requiring longer prompts. Aimed at creators, marketers, and power users who want Claude to behave like a long-term thinking partner rather than a stateless chatbot.
