vir vs flywheel-memory

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.; flywheel-memory: Flywheel is a local-first memory layer for AI agents that works with Obsidian and plain Markdown. It provides grounded search across your notes, safe reversible writes, and local indexes that keep your data on your machine. Built for users who want AI to interact with their notes without sending data to the cloud.
