pensyve vs compass

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.; compass: Compass is a context engine that builds a temporal knowledge graph connecting entities, relationships, and documents across systems. It provides AI-native capabilities, hybrid search, impact analysis, and an open type system. It can be used to query and traverse organizational knowledge for humans and AI agents.
