TL;DR
Anthropic released Claude Cowork as a research-preview agent that brings Claude Code’s abilities to a simpler, file-focused interface aimed at nontechnical users. In hands-on tests it handled tasks like sorting files, converting formats, tidying email, and interacting with a browser, though it requires careful permissioning and has known security risks.
What happened
Anthropic this week made Claude Cowork available as a research preview that adapts the company’s Claude Code capabilities into a more approachable agent for everyday file and desktop tasks. A reporter tested Cowork on macOS and found it competent at organizing desktop screenshots into month-labeled folders, converting and compressing files, generating reports, and interacting with Gmail and Google Calendar. Cowork runs only with an internet connection, appears as a “Cowork” tab alongside chat and code modes in the Claude macOS app, and labels interactions as "tasks." The tool operates inside a virtualized environment and asks users to grant access to specific folders before reading, writing, or deleting files. It can also navigate web pages with user permission, but Anthropic designed safety measures — including prompt-injection detection and permission prompts — and explicitly warns against exposing sensitive data. The preview is limited to subscribers of Anthropic’s $100-per-month plan.
Why it matters
- Represents a step toward practical, agent-driven automation for common desktop chores rather than experimental developer tools.
- Lower technical barrier could broaden use of agentic assistants beyond developer audiences.
- Demonstrates the trade-off between productivity gains and security risks around file access and web interactions.
- Offers a model for staged rollouts (research preview to paid subscribers) that lets the company iterate based on user feedback.
Key facts
- Cowork is a user-facing offshoot of Anthropic’s Claude Code, retooled for less technical users.
- Available as a research preview to Anthropic subscribers on the $100-per-month plan.
- Currently accessible only via the Claude macOS app and requires an internet connection to run.
- Sessions in the app are presented as “tasks” and a Cowork tab appears alongside Chat and Code.
- Cowork can organize files, convert formats, generate reports, interact with a browser, and manage email and calendar actions.
- The agent runs in a virtualized environment and requires explicit folder permissions before it can see or modify files.
- Anthropic implemented safety mitigations such as prompt-injection detection and user permission prompts for web actions.
- The agent will not complete purchases autonomously; in testing it found tickets but stopped short of buying them.
What to watch next
- Potential wider rollout beyond macOS — Anthropic notes a broader release could come later.
- Ongoing updates and bug fixes driven by user feedback during the research preview.
- not confirmed in the source: specific timelines for Windows or Linux support or enterprise feature sets.
Quick glossary
- AI agent: Software that can perform tasks or make decisions on behalf of a user, often by interacting with files, apps, or websites.
- Prompt injection: A type of adversarial input designed to manipulate an AI model into behaving in unintended ways or exposing data.
- Virtual machine (virtualization): A software-based emulation of a computer system used to isolate applications and control access to host resources.
- Research preview: An early release of software to a limited audience so developers can gather feedback and iterate before a wider launch.
Reader FAQ
Who can use Claude Cowork today?
It is available as a research preview to Anthropic subscribers on the $100-per-month plan.
Which platforms does Cowork support?
Cowork is currently available on macOS via the Claude app.
Can Cowork access and delete my files?
Yes, but only after you explicitly grant folder access; it runs in a virtualized environment that restricts access to approved folders.
Is it safe to give Cowork sensitive documents?
Anthropic cautions against exposing sensitive information and recommends using a dedicated nonsensitive folder and keeping backups.
Will Cowork make purchases on my behalf?
In testing the agent stopped short of buying tickets as a safety measure; automated purchases are not completed autonomously.
