TrueMemory vs NESTstack

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.; NESTstack: NESTstack is a monorepo providing a modular infrastructure stack for AI companions, with persistent memory, emotional continuity, and autonomous awareness. Built on Cloudflare Workers + D1 + Vectorize, it allows personality to emerge from emotional signals. It includes modules for emotions, knowledge, chat, daemon, gateway, soul, Discord, and desktop app.
