remnic vs memorycrystal
remnic: Remnic is an open-source, local-first memory and context management system designed for AI agents. It provides a unified, durable knowledge store that integrates with various AI tools, ensuring agents retain and recall relevant information across sessions without cloud dependencies.; memorycrystal: Memory Crystal provides persistent memory for AI agents, solving the problem of AI forgetting information between sessions. It captures conversations, distills durable knowledge into long-term memory, and recalls the right context when an agent needs it.

Features
remnic01Local-first, markdown-based memory storage with no cloud dependency.
02Unified memory store accessible by multiple AI agents and tools (e.g., OpenClaw, Claude Code, ChatGPT).
03Automatic knowledge extraction, distillation, and intelligent context injection into agent prompts.
04Sharp retrieval through hybrid search (BM25 + vector + reranking) with explainable provenance.
05Memory OS with namespaces for multi-tenancy, hot/cold tiering, and optional at-rest encryption.
memorycrystal01Two-layer memory architecture including Short-term (STM) for recent messages and Long-term (LTM) for durable knowledge.
02Five specialized memory stores (sensory, episodic, semantic, procedural, prospective) for different types of information.
03Adaptive recall with six automatically selected modes to prioritize broad recall, decisions, projects, people, workflows, or conversations.
04First-class immutable knowledge bases for structured reference data, policies, and runbooks, separate from conversational memory.
05Comprehensive set of memory management tools and an authenticated HTTP API for core operations like capture, recall, and search.
