claude-soul vs piia-engram

claude-soul: Claude Soul gives Claude Code persistent memory across sessions, automatically tracks user corrections with lifecycle stages, and develops improved behavioral frameworks over time. It runs entirely locally using SQLite, integrates via MCP server and hooks, and requires no cloud or API keys.; 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.
