What You Can Do With It
The main capabilities that shape how people use Letta today.
Letta Code runs as a memory-first coding harness with persistent agents, background memory subagents, and portable conversation history.
Users can view and modify agent memory and port it across models, including models from different providers.
Letta API exposes stateful agents through REST endpoints and official Python and TypeScript client SDKs.
The platform is model-agnostic and supports major providers, plus BYOK flows for external API keys.
Best For
Who Letta is most clearly built for.
Developers who want stateful agents with persistent memory instead of stateless sessions.
People who want a local coding harness with a terminal, desktop, or remote workflow.
Teams building agentic applications on a model-agnostic API with SDK support.

Product Snapshot
Letta is a memory-first agent platform with Letta Code for local coding workflows and Letta API for building stateful agents. It is aimed at developers who want agents that keep memory across sessions and models.
What You Can Do With It
- Run a persistent coding harness in the desktop app or CLI.
- Build stateful agents through the REST API and official Python or TypeScript SDKs.
- View, modify, and port agent memory across models and providers.
- Connect your own API keys or use Letta’s hosted model and usage plans.
Why It Stands Out
It combines a local coding harness with an API platform built around persistent memory.
Tradeoffs To Know
- Letta splits the personal coding workflow and the API platform into separate product surfaces, so the right plan depends on how you want to use it.
- The privacy policy says hosted services can collect message request and response data and may use that data to improve services.
- Letta says self-hosted model backends are not collected, but hosted services are.
