Anthropic's AI assistant Claude now carries a unified memory system that syncs across its chat interface and the Cowork tool. The company says the feature gives users control over how sensitive data is handled through settings.
The memory system is a single, persistent store that follows the assistant across different parts of the product. So a conversation started in the chat window can carry context into Cowork, Anthropic's collaborative workspace feature.
How the memory sync works
Instead of each tool keeping its own separate history, Claude now draws on one shared memory. That means details from a chat session are available when you move to Cowork, and vice versa. The goal is to reduce the need to repeat yourself or re-explain context every time you switch tools.
According to the announcement, the sync is automatic. The memory is part of the assistant's underlying behavior, not something you switch on per project. It just works across both surfaces.
User control over sensitive data
Anthropic also built in settings that let users decide how sensitive data is handled. The controls are meant to keep certain information out of the unified memory or limit what gets synced. The exact range of options wasn't detailed in the announcement, but the company says the controls are user-driven.
This is a notable step for anyone who uses Claude for work involving private or confidential material. The settings give a way to keep that kind of data from following you across tools.
What this means for existing users
For people who already use Claude in chat and in Cowork, the change is immediate. The memory is now active, so there's no need to update anything. The feature is part of the current product, not a future beta.
The announcement doesn't say whether the memory system behaves differently across plans, or if the controls have any limits. It also doesn't specify how the sync handles data from deleted conversations or what happens to memory when a workspace is cleared.
Anthropic hasn't said whether this will be extended to other Claude tools or if the controls will be expanded over time. For now, the system is live in chat and Cowork, with user settings available for sensitive data.
