Obsidian

Obsidian is my canvas because it’s local, private, and everything is just markdown files on my machine. That makes it perfect for Claude Code: markdown is easy for LLMs to understand, and Claude can directly search and manipulate the vault through normal file operations.

Pros

+Local and private knowledge base
+Markdown-first format is LLM-friendly
+Works directly with Claude Code via the file system (no extra server needed)

Cons

-You need to maintain your vault structure and habits for it to stay useful
