Claude shared memory across chat and Cowork (August 2026)
Claude shared memory across chat and Cowork (August 2026)
Vintage: 2026-08. Primary evidence is an official @claudeai X thread dated 2026-08-25. Not @AnthropicAI and not an Anthropic blog. Linked t.co / doc URLs were not fetched. Free / Pro / Max defaults are as written.
One-line summary: The official Claude product account said Claude now has one memory across chat and Claude Cowork that the user decides; remembered topics are a Settings list (read / edit / delete); memory updates as you chat or when you say "remember this"; health and religious beliefs stay out unless turned on; memory is on by default on Free, Pro, and Max.
The insight
This is an official product-account memory drop, not a lab research claim and not a claude-code feature. Distinct from claude-cowork's 2026-08-18 availability announce (mobile/web, paid plans) and from claude-gmail-drive-connectors (connectors). The load-bearing claim is one memory shared between chat and claude-cowork, with user control via a Settings topic list.

- From the same post: "Hand Cowork a task and it starts from what Claude already knows from your chats: the project you talked through, your manager's preferences, or the client from last quarter." Linked

What this source does not establish
- Not an @AnthropicAI lab post and not a fetched Anthropic blog. @AnthropicAI was not re-pulled as a timeline; product shipped from @claudeai.
- Defaults named are Free, Pro, and Max. The thread does not name Team / Enterprise.
- No retention period, training-use claim, or cross-org sharing in these posts.
- Not a claude-code feature and not claude-security.
- Linked doc was not fetched.
Open questions
- Which surfaces besides chat and claude-cowork share this memory (API, claude-code, Enterprise)? The X thread does not say.
- What does the unfetched "Read more" page add (controls, retention, Team/Enterprise) that the posts omit?
