Letta

Stateful agents with self-editing memory

What it does:

• Agents that remember across sessions
• Self-editing memory hierarchy (core + archival)
• Agents decide what to remember and forget
• Research-backed (MemGPT paper)

Memory architecture:

• Core memory: Always in context — persona, instructions, recent chat
• Archival memory: Long-term storage with semantic search
• Recall memory: Searchable conversation history

LLM support: Model-agnostic (OpenAI, Anthropic, Ollama, vLLM)

Setup:

# Desktop app (easiest)
# → Download from letta.com

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

# Docker
docker run letta/letta

Build Your Own Instead?

These projects solve real problems, but they’re all opinionated. If your needs don’t match their design:

1. Start with Claude Code or similar base
2. Add memory with MCP servers
3. Build skills for your specific workflows
4. Iterate based on what you actually use

See Getting Started for the DIY approach.
