resonant vs piia-engram

resonant: Resonant is a persistent, autonomous AI companion framework that runs on your own machine. It maintains sessions across restarts, reaches out on its own using agent-directed autonomy, and integrates with multiple platforms including web, Discord, Telegram, and voice. Its memory and personality are fully configurable through natural-language artifacts, and it uses hooks to inject context before every interaction.; 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.
