piia-engram vs sugar

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.; sugar: Sugar provides persistent memory for AI coding agents across sessions and projects. It stores decisions, patterns, and preferences to avoid re-explaining context. It also includes a task queue for autonomous task execution.
