nex-as-a-skill vs subcog

nex-as-a-skill: Nex is an intelligence layer for AI agents that provides a unified knowledge graph across different tools. It allows you to store information from one agent and recall it from any other, eliminating the need to re-explain context. It supports multiple AI platforms and integrates with various data sources.; subcog: Subcog is a persistent memory system for AI coding assistants that captures decisions, learnings, and context from coding sessions. It features a single-binary distribution, three-layer storage architecture (SQLite, FTS5, usearch HNSW), MCP server integration, and Claude Code hooks. It achieves high accuracy on factual recall benchmarks.
