Descriptions:
YouTuber Jeff Su walks through the construction of a personal AI productivity workspace he calls “Cowork,” built on top of Claude using a structured hierarchy of CLAUDE.md configuration files and persistent memory markdown files. The system solves a common pain point with Claude workflows: context and preferences reset every session, forcing users to re-explain their working style and active projects each time they open a new conversation.
The architecture Su builds mirrors a constitutional structure — a root CLAUDE.md file sets workspace-wide behavioral rules (analogous to a national constitution), while individual “workstations” for email, newsletter writing, and personal finance each carry their own configuration files that inherit from and extend the root level. A separate memory.md file is maintained and updated by Claude itself across sessions, tracking active projects, deadlines, and learned preferences so each new conversation picks up where the last one ended. A voice principles file, generated by having Claude analyze 30 sent Gmail messages, allows the system to draft content in the user’s natural tone.
The video demonstrates the full system handling real tasks: parsing a credit card statement for spending analysis, drafting a newsletter from rough talking points in the creator’s voice, and managing a to-do list — all via natural language. Su provides starter templates for the CLAUDE.md, memory.md, and voice principles files, making this a practical beginner entry point for anyone wanting a more persistent, personalized Claude workflow without writing custom software or using an API directly.
