Letta (formerly MemGPT) is an open-source platform for building stateful AI agents with persistent memory that learn and self-improve over time. It ships as an npm-installable agent harness with an interactive terminal UI, an app server for self-hosting, desktop/web apps, chat channels (Slack, Discord, Telegram), and a TypeScript Agent SDK.
Use cases
- build stateful AI agents with long-term memory
- create a personal AI assistant that remembers me across sessions
- self-host an agent server with persistent identity and memory
- run an AI coding agent in the terminal
- connect an agent to Slack, Discord, or Telegram
- build agents that learn and improve from experience over time
- schedule proactive background agent tasks
When to choose
- you need agents with persistent memory and continual learning rather than stateless LLM calls
- you want a self-hosted agent runtime plus ready-made terminal, desktop, and web clients
- you want agents reachable through existing chat channels like Slack or Discord
- you're building TypeScript apps and want an SDK for embedding stateful agents
When to avoid
- you only need simple stateless LLM API calls without memory
- you need a lightweight library with minimal runtime footprint
- you require the retired Letta V1 API server, which is unsupported and archived
- you want a framework locked to a single model provider's managed stack
