Cowork: Let Claude Work in Your Files

Anthropic introduced Cowork, a research-preview feature that lets Claude autonomously work in a user-selected folder on macOS. Built on Claude Code’s agent foundations, it streamlines workflows, supports connectors and skills, and can operate with the browser via Claude in Chrome. Safety controls, user permissions, and cautions around destructive actions and prompt injections are emphasized, with more features and platforms coming soon.

Key Points

  • Cowork gives Claude controlled file-system access to a user-selected folder to autonomously read, edit, and create files.
  • It’s built on Claude Code’s agent foundations, supports connectors and new skills, and can use the browser via Claude in Chrome.
  • Designed for streamlined workflows: persistent context, correct file outputs, and queued tasks that run in parallel.
  • User control and safety are central—explicit permissions and confirmation for major actions—yet risks like deletions and prompt injections require caution.
  • This is a research preview with rapid iteration planned (cross-device sync, Windows), available now on macOS for Claude Max subscribers.

Sentiment

The overall sentiment is cautiously optimistic and highly interested. Hacker News commenters largely agree with the utility and market need for Cowork, especially for non-developer tasks, validating Anthropic's direction. However, this positive reception is balanced by a healthy skepticism regarding the necessity of automating overly simple tasks, concerns about the social implications of AI-generated work, and specific technical critiques regarding image understanding and promotional accuracy.

In Agreement

  • The concept of AI 'agents for other people' makes significant sense, as users are already extensively employing Claude Code for diverse non-developer tasks like expense classification, invoice generation, and scheduling.
  • Anthropic has successfully developed a robust underlying framework, described as the 'best harness,' for enabling these agentic capabilities.
  • Building a dedicated, user-friendly UI like Cowork is a logical and necessary step to expand adoption beyond technical users and achieve broader 'genpop' appeal.
  • The agent's ability to directly interact with the local file system (reading, editing, creating files) is a powerful and highly valued feature.
  • Some users have experienced positive and detailed results with Claude's image understanding, challenging the common perception of it as a weakness.
  • The automation of mundane and repetitive tasks, such as organizing files or generating reports, is seen as highly valuable for improving efficiency.

Opposed

  • Concerns were raised about the necessity of automating very simple tasks like desktop organization or calendar checks, arguing that humans can easily perform these or that existing tools already provide adequate solutions (e.g., Apple's desktop stacks).
  • Questions were posed regarding the social and ethical implications of rapidly creating work products, such as presentations, with AI, potentially making human effort seem less sincere.
  • Skepticism was expressed about the accuracy of promotional videos, suggesting that Claude interacts with the desktop using command-line tools for file management rather than genuine visual interpretation of screenshots, pointing to a perceived weakness in Claude's image understanding.
  • The general perception of Claude Opus 4.5 having weaknesses in detailed image understanding was a point of concern, despite counter-examples from other users.
