If you use Claude Code, Codex, or Cursor, every new session starts cold — re-explain your project, re-set preferences, re-establish context. Piia Engram is a local-first MCP memory layer that gives every AI coding tool a shared starting point: your approved lessons, decisions, preferences, and project knowledge. No cloud. No vendor lock-in. You review before anything becomes permanent. Open source, Apache 2.0.
