Lisa – Long Term Memory for Claude

Lisa Simpson - the overachiever who never forgets a fact, a detail, or a saxophone lesson.

---

Why Lisa?

Unlike simple vector databases or file-based memory, Lisa uses Graphiti - a knowledge graph that captures relationships between concepts, not just text.

• Graph-native storage (Neo4j) - Connections matter as much as content
• LLM-powered extraction - Automatically identifies entities and relationships
• Temporal awareness - Knows when you learned something
• Semantic retrieval - Finds relevant context by meaning, not keywords

---

To Install

From your console

npm install -g @tonycasey/lisa

then in any folder you want to work with, open your console and type

lisa setup

Using Lisa

Once installed, Lisa works automatically. Your AI assistant will:

1. Load context at session start - Previous memories and project context
2. Capture important info during coding - Decisions, patterns, etc.
3. Remember explicitly when asked - Say "remember that..." to save important notes

Explicit Memory Commands

During a Claude Code session:

• "remember that we decided to use Redux for state management"
• "hey lisa, what do you know about the authentication system?"
• "lisa, show me recent memories"
• "lisa, what tasks are we working on?"
