iai-mcp vs m3-memory

iai-mcp: IAI-MCP is a local memory layer for MCP-compatible AI assistants. It captures every conversation turn verbatim, organizes them over time, and serves relevant memories at the start of new sessions. All data is encrypted locally with AES-256-GCM and never leaves your machine.; m3-memory: M3 Memory provides persistent, local memory for MCP agents using SQLite, hybrid retrieval, and optional cross-device sync. It stores facts, decisions, and preferences across sessions, with contradiction handling and knowledge graph features. It works offline and integrates with Claude Code, Gemini CLI, and other MCP-compatible agents.
