Claude Code is brilliant—but it's a goldfish. Every session starts from zero.
The cost of context loss:
Give Claude Code a permanent memory — 100% local, zero config, graph-powered
"Claude Code starts every session with zero context. There is no memory of previous sessions, previous work, or accumulated understanding of the user's projects and preferences." — GitHub Issue #14227
Claude Graph Memory fixes this.
A 100% local knowledge graph that runs alongside Claude Code, automatically indexing your documentation and code structure. Claude queries this graph to understand your project deeply, and stores learnings that persist forever.

Most local RAG tools use vector databases for semantic similarity. But codebases aren't about "similar text"—they're about relationships.
Graphs preserve the structure of your project, not just the text.
Knowledge graphs offer transparent reasoning paths—if Claude gives you a wrong answer based on project context, you can open the graph browser at localhost:7474 and see exactly which node fed the hallucination.
/docs folder/docs:ProjectName:Document)# Clone the repo
git clone https://github.com/amarodeabreu/claude-graph-memory.git
cd claude-graph-memory
# Run the installer
./install.sh
That's it! The installer will:
neo4j Python driverclaude-graph CLI command./verify.sh
After installation, restart Claude Code to load the MCP servers. Then navigate to any project with a /docs folder—it will auto-populate on session start.
Start a new session; Claude queries the graph for recent decisions and project context without you re-explaining anything.
MATCH (d:MyProject:Document)-[:DESCRIBES]->(c:Component {name: 'AuthService'})
RETURN d.path, d.title
One query returns all docs, decisions, and code touching authentication.
Store a memory node that persists across all future sessions—Claude will know about it tomorrow, next week, forever.
Open localhost:7474, inspect the graph, and see exactly which nodes Claude used to make its recommendation.

No. Everything runs locally:
Minimal. The graph database is very efficient:
Currently designed for single-machine use. For multi-machine sync, you'd need to:
Yes! It only indexes local files. Nothing leaves your machine.
Works fine, but initial population may take a minute. Incremental updates are always fast.
Yes! See CONTRIBUTING.md for how to add language support.
CLAUDE.md loads everything into the context window every session—competing for precious tokens. Claude Graph Memory provides targeted retrieval: Claude queries only what's needed, when needed. Plus, graphs capture relationships that flat markdown can't express.
Vector databases excel at "find similar text." But for code, you often need structural queries: "what functions are in this file," "which decisions affect this component," "show me everything connected to AuthService." Graphs model these relationships explicitly; vectors can only approximate them.
Contributions are welcome! See CONTRIBUTING.md for guidelines.
