Anthropic consolidated its product interfaces on 16 September, retiring Claude Cowork and replacing it with Claude Docs and Claude Slides. Docs supports collaborative document drafting with threaded comments; Slides creates, edits, and presents decks exportable as PDF or PowerPoint. The stated driver: users were routinely selecting the wrong interface before their work could begin, creating friction across the fragmented surface. Rollout starts with Pro and Max subscribers, with free and team tiers to follow. The launch positions Anthropic directly against Google Workspace and Microsoft 365 Copilot on the productivity layer — not as a chatbot API but as an integrated office suite with shared context across email, documents, and presentations. Claude Slides in particular targets Copilot's strongest consumer use case. Combined with the earlier release of Claude for Email, Anthropic is assembling a full productivity stack that competes on the application layer, not only the model layer.
