Letta creates stateful agents that remember everything and improve themselves over time. Unlike traditional stateless chatbots, Letta agents develop unique personalities and experiences, evolving with your needs.

Key capabilities:

Persistent Memory: Each agent maintains its own memory palace, storing experiences and context that persist across conversations. You can transparently view, modify, and port memory between different AI models and providers.
Continuous Learning: Background memory subagents automatically improve prompts, context, and skills based on real interactions, making your agent smarter with every conversation.
True Personalization: Build deeply personalized agents with distinct personas that learn your preferences and adapt to your workflow over time.
Cross-Device Access: Chat from your desktop app, terminal, or any device. Use letta server to remote control agents running on external machines while keeping their memory and context intact.
Flexible Integration: Connect your own API keys and coding plans, or use Letta's infrastructure. Port agents between machines and different AI model providers without losing their learned experiences.
Developer-Friendly: Access through the desktop app, terminal interface, or SDK for custom integrations. Requires Node.js 18+ for installation.

Letta transforms how you interact with AI by creating agents that genuinely remember your history, learn from interactions, and become more valuable over time.
