letta vs recallium
letta: Letta is a powerful platform for building stateful AI agents equipped with advanced memory, enabling them to learn and self-improve over time. It provides both a command-line interface for local agent execution and a comprehensive API with Python and TypeScript SDKs for seamless integration into applications.; recallium: Recallium is a persistent memory layer for AI coding agents, delivered as an MCP server. It provides typed, project-scoped memories that survive across sessions, with intelligent search tuned for engineering queries. It supports Claude Code, Cursor, Windsurf and other MCP-compatible tools.
