neurostack vs overmind

neurostack: NeuroStack is a self-hosted MCP server and CLI that indexes Markdown vaults by meaning, providing AI agents with persistent memory across sessions. It detects stale notes, supports semantic and keyword search, and uses tiered retrieval to minimize token usage. Fully local, it never modifies your files.; overmind: Overmind is the first open-source event-driven AI agent cognitive architecture that serves as an external brain for Claude Code. It provides permanent memory, multi-window fleet collaboration, and pre-answer self-checking to eliminate hallucinations and rework.
