ctx-open vs widemem-ai

ctx-open: CTX is a cognitive version control system for AI agents, preserving structured reasoning artifacts as durable state instead of ephemeral chat transcripts. It enables agents to maintain continuity across sessions, track decisions, and reproduce reasoning paths. The system includes a CLI, a local MCP server, and a web viewer.; 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.
