Claude Cowork comes to every conversation

We're rolling out a new Claude experience that makes everything Claude Cowork does available from any conversation. Ask a quick question or hand Claude a bigger task, like a report, spreadsheet, or presentation, without choosing a mode first. Your chats, Cowork tasks, projects, connectors, and skills carry over. The new experience is rolling out gradually to Pro and Max plans on web, desktop, and mobile. Learn more in Claude Cowork and chat are one Claude.

Create designs, decks, and docs in any conversation

You can now ask for a design, deck, or document in any conversation with Claude, including in Claude Code and the Artifacts tab, and edit it with Claude or directly as you work. Claude Design works inside your conversations with all of its features, including on-canvas editing and importing your design system. Claude Slides gives presentations their own starting point, and Claude Docs is a new way to write living documents with Claude and your team. Artifacts, including Claude Design, Claude Slides, and Claude Docs, are available on every plan, including Free. On Enterprise plans, Claude Design, Claude Slides, and Claude Docs are in beta and off by default until an owner turns them on. Learn more in What are artifacts and how do I use them? and Get started with Claude Docs.

Smart reports (beta)

We’ve launched smart reports, which analyze how a team uses Claude and report on the work getting done, what it costs, where sessions run into friction, and which repeated patterns are worth packaging as shared skills.

Memory is on by default for Free, Pro, and Max plans and off by default for Team and Enterprise organizations. See Use Claude's chat search and memory to build on previous context.

Skill and plugin security scanning (beta)

Enterprise plans can now turn on skill and plugin security scanning to automatically check third-party skills and plugins for malicious content when someone uploads or edits them. For more information, see Get started with skill and plugin scanning.
