pensyve vs nex-as-a-skill

pensyve: Pensyve is a universal memory runtime for AI agents that eliminates amnesia across sessions. It offers three memory types (episodic, semantic, procedural), 8-signal fusion retrieval, and FSRS-based forgetting curve. Framework-agnostic with SDKs for Python, TypeScript, Go, and integrations with LangChain, CrewAI, AutoGen, plus native plugins for Claude Code, Cursor, and VS Code.; 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.
