TrueMemory vs lumen

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.; lumen: Lumen is a 100% local semantic code search engine for AI coding agents. It uses open-source embedding models, SQLite, and your CPU to provide fast and cost-effective code understanding. No API keys or cloud required.
