About Contextual Memory Cloud
Contextual Memory Cloud provides persistent memory services for AI agents and applications, enabling them to store, retrieve, and reason over context across sessions. It offers a cloud API that handles memory management including semantic search, temporal ordering, relevance scoring, and memory consolidation. The platform is designed for developers building AI agents that need to remember past interactions, maintain user context, and build long-term knowledge — capabilities that standard LLM APIs lack. It addresses the fundamental limitation of stateless AI by providing a managed memory infrastructure.

Learn MoreCognee
Cognee is an open-source framework that builds knowledge graphs from your data so AI systems can reason over connected information rather than isolated text chunks. It processes documents, databases, and unstructured data into a structured knowledge graph that captures entities, relationships, and context. This enables more accurate and contextual AI responses compared to simple vector search. Cognee supports various graph databases and integrates with LLM frameworks like LangChain and LlamaIndex, making it a key building block for developers creating AI applications that need deep understanding of interconnected data.
