iai-mcp vs vir

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.; vir: Vir reads Claude Code session transcripts, distills durable knowledge into typed Markdown notes in your Obsidian vault, and feeds the best insights back into CLAUDE.md files. It treats Obsidian as the primary frontend with deep integration, supporting retroactive processing of existing sessions. The tool includes confidence scoring, opt-in sync, MCP server, and upcoming Obsidian plugin.
