Overview
- Claude Cowork is a research preview available now only in the Claude macOS app for Claude Max subscribers priced roughly $100–$200 per month, with a waitlist for others.
- Users grant Cowork access to a designated local folder so Claude can read, edit, and create files, plan and execute multi‑step tasks, queue work in parallel, and use connectors or a Chrome plugin for web and app integrations.
- Anthropic warns the agent can take potentially destructive actions if instructions are unclear and remains vulnerable to prompt‑injection attacks, though it includes folder‑level permissions and prompts before significant actions.
- Cowork is built on the same foundations as Claude Code, and Anthropic engineer Boris Cherny says the feature was written largely by Claude Code itself to accelerate development.
- Anthropic says it will iterate based on preview feedback with planned cross‑device support and a Windows release, a push that broadens its productivity footprint and could challenge offerings from Microsoft, OpenAI, and specialist startups.
