widemem-ai vs ChatCrystal

widemem-ai: widemem is an open-source AI memory layer that provides persistent, locally-stored memory with importance scoring, time decay, hierarchical recall, and YMYL prioritization. It resolves conflicts, admits uncertainty, and supports multiple LLM and embedding providers, making it ideal for building AI assistants that remember what matters.; ChatCrystal: ChatCrystal collects conversations from AI coding tools, distills them into structured notes with LLMs, and builds a local searchable knowledge base from your real problem-solving history. It supports multiple sources like Claude Code, Cursor, Codex CLI, Trae, and GitHub Copilot, and offers desktop app, CLI, and Docker deployment options.
