Letta Code: The First Memory-First AI Coding Agent

Unlike session-based assistants, this agent remembers your preferences and coding patterns across every conversation.

Letta Code: The First Memory-First AI Coding Agent

Every AI coding assistant you've used forgets you the moment you close it. Cursor starts fresh. GitHub Copilot has no memory of yesterday's conversation. Claude forgets your preferences between sessions.

Letta Code changes this fundamentally. It's the first memory-first coding agent that persists across sessions and learns over time.

The Memory Problem

Traditional AI coding tools are stateless. Each interaction is isolated — they can't remember:

  • Your preferred coding style
  • Previous conversations about the codebase
  • Patterns in how you like to structure code
  • Context from last week's debugging session

This forces you to constantly re-explain context, repeat preferences, and rebuild understanding with every new chat.

How Letta Code Works Differently

Built on the Letta API, Letta Code maintains a persistent agent that accumulates knowledge about you and your projects. It remembers:

  • Your coding patterns — how you prefer to structure functions, name variables, handle errors
  • Project context — the architecture decisions you've made, why certain approaches were chosen
  • Past conversations — previous debugging sessions, feature discussions, refactoring decisions
  • Skill acquisition — new techniques it learns while working with you

The agent works with multiple AI models (Claude, GPT-4, etc.) but maintains continuity regardless of which model powers individual responses.

Why This Matters Now

We're seeing AI coding mature from demo tools to production partners. The infrastructure wave is here — developers are building the boring but essential middleware that makes AI coding actually usable at scale.

Letta Code represents a fundamental architectural shift. Instead of treating AI as a stateless utility, it becomes a persistent coding partner that grows more useful over time. The more you work together, the better it understands your preferences and codebase.

This is what collaborative programming with AI should feel like — not starting from scratch every time, but building on shared history and understanding.

Try Letta Code — it's open source and ready to remember everything.
