Claude Cowork adds persistent knowledge bases for ongoing project memory

This reply frames Claude Cowork’s new Knowledge Bases as persistent, topic-specific memory vaults.

Instead of dumping context once per session, users can store preferences, decisions, facts, and hard-won lessons in a reusable knowledge base.
Cowork then pulls that information in automatically during the workflow, making the assistant feel more continuous and less like a stateless chat window.

It’s a product-positioning update more than a technical deep dive, but it makes the feature’s intent clear: reduce repeated context loading and keep work grounded in durable project memory.
