# Anthropic launches Claude Cowork

Full title: Anthropic launches Claude Cowork — "Claude Code for the rest of your work"

On January 12, 2026 Anthropic launched Claude Cowork as a research preview in the Claude Desktop macOS app. It is a general agent for non-developers: it works in user-granted local folders, plans, splits tasks into parallel subtasks, and delivers finished files such as spreadsheets, decks and documents. It reached Pro users on Jan 16 and general availability on April 9.

## Key facts
- Research preview Jan 12, 2026 for Max subscribers; Pro access from Jan 16
- Built on the Claude Code agent harness, with a visual interface in Claude Desktop
- General availability around April 9, 2026 with enterprise features
- Merged with regular chat into 'one Claude' on Sept 16, 2026

## What happened

Anthropic says Cowork grew out of users repurposing Claude Code for non-coding tasks. It pulls from local files, cloud tools and the web, and it can run several tasks at once.

## Why it matters

It took Claude Code's agentic pattern to mainstream knowledge work, and it became one of Anthropic's biggest product lines of 2026.
