Anthropic has enabled default shared memory between its chat assistant Claude and work tool Cowork, making cross-product memory transfer automatic unless users opt out. This shift impacts user privacy and convenience, with further details still emerging.

Anthropic has enabled shared memory by default between its AI products, Claude and Cowork. This change means that information the assistant learns about a user will now automatically carry over between the chat and work automation tools unless users actively opt out, shifting the privacy default from opt-in to opt-out.

The update was announced by Anthropic in August 2026, with the company stating that users can now review and disable memory sharing in the settings of Claude. Previously, memory was scoped narrowly, requiring users to manually enable sharing between products. Now, the default is to share all memories unless explicitly turned off, impacting anyone using both products with memory enabled.

Memory shared across Claude and Cowork can include preferences, ongoing projects, or personal details shared in conversations. Anthropic describes shared memory as a convenience feature designed to reduce repetitive input and improve assistance quality, especially for complex, multi-step tasks.

However, many specifics remain unclear: it is not confirmed whether users can selectively share certain memories, whether existing memories automatically migrate, or how deletion in one product affects the other. The company has indicated that users can disable sharing via settings but has not detailed granular controls or the scope of data transfer.

Implications for User Privacy and Convenience

This change significantly impacts user privacy because default sharing means personal and professional information can now flow freely between the chat and work automation tools. For users prioritizing data separation, this necessitates proactive management of settings. Conversely, for those seeking seamless assistance, the default enhances convenience by reducing repetitive input across products.

Industry observers note that this move aligns Anthropic with broader industry trends where AI providers expand memory capabilities, but it also raises privacy concerns and questions about data use, retention, and control. The shift could influence user trust and industry standards around AI memory management.

Background on Anthropic’s Memory Features

Anthropic introduced memory for Claude to allow the assistant to retain information across conversations, such as user preferences, recurring projects, or writing styles. This feature was designed to be inspectable, enabling users to review and delete stored memories. Meanwhile, Cowork is Anthropic’s agentic AI, capable of executing multi-step work tasks like research, drafting, and coordination.

Initially, memory was scoped narrowly, and users had to manually enable sharing between Claude and Cowork. The recent change shifts this to a default, making cross-product memory sharing the norm for most users. This development occurs amid industry-wide debates over AI memory, with competitors like OpenAI and Google expanding persistent memory features and facing similar privacy questions.

“Users can opt out of memory sharing between Claude and Cowork in settings.”

Details Still Unclear About Memory Management

Several key questions remain unanswered: It is not confirmed whether specific memory types are selectively shared or if all data migrates automatically. The scope of what can be pruned or kept private before transfer is also unknown. Additionally, it is unclear whether shared memories are used for model training, how deletion in one product affects the other, or if users can set granular preferences for different categories of information. The timing of full rollout and whether administrators can control these settings for managed accounts have yet to be clarified.

Next Steps for Users and Industry Response

Users should review their Claude and Cowork settings this week to ensure their preferred privacy level. Anthropic is expected to provide further clarification on selective sharing, data retention, and training policies soon. Industry observers will watch how competitors respond as shared memory becomes a key differentiator in AI assistant capabilities. Future updates may include more granular controls, enhanced privacy options, and broader transparency about data use.

Key Questions

Can I choose what memories are shared between Claude and Cowork?

It is not yet confirmed whether users can selectively share memories. Currently, the default is to share unless the user disables it in settings, but details about granular control are still emerging.

How do I disable memory sharing between the products?

Users can go to Claude’s settings to turn off memory sharing. The exact steps are expected to be detailed in upcoming updates from Anthropic.

Will shared memories be used for training or improving the models?

Anthropic has not specified whether shared memories are used for model training or other purposes. Further clarification from the company is anticipated.

What happens if I delete a memory in one product?

The impact on the other product remains unclear. It is not confirmed whether deletion in Claude or Cowork automatically removes the memory from the other or if it requires separate actions.

When will the full rollout and feature details be available?

The rollout is ongoing, and Anthropic is expected to provide further details and updates in the coming weeks.
