Rails agent memory patterns
Agents that forget context frustrate users. Memory should be explicit: what is stored, for how long, and for whom.

Direct answer
Rails Agent supports memory patterns so agents can retain conversation and user context across turns, while knowledge retrieval covers durable documents. Choose thread memory for a session, longer-lived memory for a user or org, and knowledge for policies and manuals.
Pattern map
- Thread/session memory for the current conversation
- User or organization memory for preferences and facts
- Knowledge bases for documents and policies
- Avoid stuffing entire histories into every prompt without truncation policy
Privacy note
Memory is data. Apply the same retention and access rules you use for Rails models that store customer information.
Frequently asked questions
Is memory the same as RAG?
No. Memory stores interaction state; RAG retrieves documents. Production agents often need both.
Where is memory documented?
See /docs/memory for product details and configuration.
