engram vs overmind

engram: Engram is a local identity layer for AI tools that stores your profile, preferences, lessons learned, and key decisions as local JSON files. It exposes them through MCP so every AI tool reads the same context, persisting across sessions, tool updates, and switches. 100% local and open source.; 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.
