pensyve vs yantrikdb-server

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.; yantrikdb-server: YantrikDB is a cognitive memory engine designed for AI agents that goes beyond vector databases by implementing forgetting, consolidation, and contradiction detection. It provides token-efficient recall, proactive triggers, and a comprehensive API for memory operations, making it suitable for persistent AI systems.
