TrueMemory vs vir

TrueMemory: TrueMemory is a neuroscience-inspired persistent memory system for AI agents. It achieves state-of-the-art scores on LoCoMo, LongMemEval, and BEAM benchmarks while running entirely offline on a single SQLite file. The six-layer retrieval pipeline with an encoding gate filters noise and stores only meaningful information.; 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.
