TrueMemory vs subcog

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.; subcog: Subcog is a persistent memory system for AI coding assistants that captures decisions, learnings, and context from coding sessions. It features a single-binary distribution, three-layer storage architecture (SQLite, FTS5, usearch HNSW), MCP server integration, and Claude Code hooks. It achieves high accuracy on factual recall benchmarks.
