AI agent for knowledge work, built with Claude Code in 10 days
Product AnnouncementAnthropic launched Labs, an experimental features platform, alongside Claude Cowork — a general-purpose AI agent that can read, create, and manipulate files on a user's desktop. Positioned as 'Claude Code for the rest of your work,' Cowork targets non-developers for tasks like expense tracking, document drafting, and file organization. Built in ~10 days using Claude Code itself, the launch triggered a near-$1 trillion selloff in software stocks.
Cowork runs in a lightweight Linux VM on the user's machine, providing sandboxed code execution with controlled access to a workspace folder. It can read, create, edit, and organize files — turning Claude from a chat assistant into a desktop agent. The architecture mirrors Claude Code but replaces the terminal interface with a visual workspace.
Anthropic reportedly built Cowork in approximately a week and a half, primarily using Claude Code itself. This is a powerful form of product validation: the tool that builds the tool. It demonstrated that Claude Code had reached sufficient capability to bootstrap entirely new product categories.
The launch triggered a near-$1 trillion selloff in software stocks. Investors recognized that if an AI agent could handle document processing, spreadsheet creation, file management, and multi-step office workflows, it threatened the value proposition of dozens of SaaS companies. This was the market pricing in the 'AI replaces software' thesis.
