Why VaultBase

Your markdown, your rules

Standard markdown files on disk. No proprietary format, no database lock-in. Use VaultBase, Obsidian, VS Code, or vim. Export is a directory copy.

Compare with Notion →

AI that respects permissions

AI agents connect via MCP and see only what their role allows. No "AI has access to everything" — RBAC applies to agents the same as humans.

Compare with Obsidian →

Decisions that compound

Decision traces build organizational memory. Every judgment call becomes searchable precedent — with inputs, reasoning, and outcomes attached.

Compare with Confluence →
