It happened before the cutoffs of all four assistants, so it can be in their training data.

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.
