How to Add Persistent AI Memory with Letta Code CLI

Letta Code CLI brings stateful, memory-first AI agents to your terminal. Unlike traditional stateless chat interfaces that forget everything after each session, Letta agents maintain long-term memory, learn from interactions, and evolve over time — making them ideal for coding, project management, and personal assistance.

Quick Setup Guide

1. Installation
   Ensure you have Node.js 18+ installed. Then run:

   npm install -g @letta-ai/letta-code
   

2. Launch & Configure
   Run letta in your terminal. Use /connect to link providers like OpenRouter, OpenAI, Ollama (local), or others. Then select a model with /model — free options like Llama variants or Gemma often work well for testing.

3. Initialize Memory
   Create or navigate to a project folder and run letta. Use /init to let the agent deeply research your codebase or workspace. The agent builds a structured memory system (including Human.md for personal details) that persists across sessions.

4. Teach & Recall
   Explicitly add memories with /remember (e.g., “Remember my name is Mahesh”). The agent confirms updates and references them later. Ask “What’s my name?” to test recall. You can also view or manage memory blocks directly.

Why Letta Memory Stands Out

• Persistent Identity: Agents develop personality, preferences, and project knowledge over time.
• Self-Improvement: Supports skill learning, periodic “dreaming,” and memory auditing commands like /doctor.
• Flexible: Works with local or cloud models, integrates tools, and supports coding workflows.
• Project-Aware: Great for long-horizon tasks where the agent remembers codebase structure, preferences, and past decisions.

Letta Code turns one-off AI chats into reliable, learning companions. Whether you’re building software or managing daily tasks, adding memory via Letta gives your agents continuity and intelligence that grows with you.
