NEXO Brain is a local cognitive runtime that provides persistent memory, durable workflow execution, and a shared brain across multiple AI coding agents. It implements cognitive science concepts like forgetting curves, semantic search, and overnight learning to turn stateless assistants into cognitive partners. With 150+ MCP tools and support for Claude Code, Codex, Claude Desktop, and others, it enhances AI agents with long-term memory and adaptive behavior.
