piia-engram vs overmind

piia-engram: piia-engram is a local-first AI identity layer that stores your profile, preferences, lessons learned, and key decisions as local JSON files. It exposes them through the MCP protocol so that all compatible AI tools (like Claude Code, Codex, and Cursor) read the same identity, eliminating the need to re-explain yourself across sessions, tool switches, or updates.; 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.
