[Anthropic Unifies Claude Chat and Cowork Interface, Launches New Multithreaded Projects] Anthropic announced the integration of Claude Chat and Cowork into a unified interface, where Claude automatically determines and routes different types of requests. Users can utilize Chat, Cowork, Artifacts, and Claude Design within the same window without switching between tabs. The company also introduced Claude Docs and Claude Slides, which support collaborative creation of documents and presentations, allow task progress tracking on mobile devices, and enable exporting presentations as PowerPoint or PDF files. This experience will be rolled out to Pro and Max users in the coming weeks, followed by expansion to the Free and Team plans. Additionally, Anthropic is testing the new Projects feature in Claude Code.
