Why it matters
Cowork moves Claude from answering in text to acting inside a selected workspace, making file permissions and execution boundaries as important as answer quality.
Claude
Anthropic's assistant, extending long-context reasoning into file, browser, and cross-app work with Cowork.
Claude remains strong at long-document reading, careful writing, and complex reasoning, but Cowork pushes the product boundary from conversation into execution. It brings the agentic approach of Claude Code to non-coding knowledge work: within folders, browser access, and connectors selected by the user, Claude can read and modify material, organize files, and produce deliverables such as reports, spreadsheets, or presentations. Cowork is available on paid Claude plans through the desktop app, while some cloud, mobile, and remote-assignment capabilities remain in beta or gradual rollout. Permissions deserve deliberate setup. Local workspaces can use read-only, read-write, or no-delete modes, while remote sessions may send files to the cloud for processing. Limit the folder and write scope before handing over important material.
