Build your own Knowledge Base in 10 mins (FREE & Open Source)

Описание: This is an open-source personal knowledge graph built on SQLite that
connects to Claude Code, Cursor, and any AI coding agent via MCP.

make your agents 'actually useful' by providing a persistent and fluid memory that compounds.

No cloud. No vendor lock-in.

In this walkthrough:
Why Notion, Obsidian, and markdown aren't the right abstraction for AI
How a local SQLite database + MCP server gives AI agents access to
your personal context
Live demo: building a knowledge graph from scratch
The architecture: nodes, edges, dimensions, hub nodes, guides
How context engineering changes how you work with AI
