vir vs rtfm

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.; rtfm: RTFM is a local, open-source retrieval layer that indexes everything in a project (code, docs, PDFs, etc.) so that AI agents can find the right context instantly without hallucinations or cloud costs. It integrates with Claude Code and other MCP clients, supports multiple formats, and provides fast search with progressive disclosure.
