🧠 Memory & Context
Memory and context tools give agents persistence — long-term recall, user preferences, and knowledge that survives across sessions. The difference between a demo and a product is usually in this layer.
Acontext
Manages agent skills and long-term memory as a layered data structure for persistent context.
Agentage Memory
Cross-vendor shared memory layer exposed as a remote MCP server at `memory.agentage.io/mcp` (Streamable HTTP, OAuth 2.1 + PKCE + DCR) that Claude, Cursor, and ChatGPT read and write as plain markdown you own.
Chroma
Lightweight, embeddable vector store for building memory-augmented AI agents with fast semantic retrieval.
cognee
Knowledge engine for AI agent memory, set up in 6 lines of code with graph-based knowledge extraction.
Cortex Memory
Full-stack solution for agent memory covering extraction, vector search, and optimization.
Pinecone
Managed vector database with agent namespaces for multi-tenant isolation, hybrid search (vector + keyword), serverless auto-scaling, and $11B valuation.
How to choose memory & context
- Decide between managed memory services and self-hosted stores
- Check retrieval quality, not just storage features
- Look for privacy controls and per-user data isolation
Common use cases
- Persistent user memory across agent sessions
- RAG pipelines grounding agents in private data
- Long-horizon task state for multi-day workflows
