The Claude Co-work team at Anthropic stays close to user feedback through traditional UXR, internal dogfooding, a running Slack channel, and monitoring social media and passionate users.

Jenny Wen uses Claude Co-work for most of her design tasks at Anthropic, excluding very nitty-gritty production code work.

Anthropic integrated the Claude Code desktop app into the traditional Claude app, alongside Claude chat and Claude Co-work.

Anthropic has been using the Claude Mythos model internally since February 24th, 2026.

The idea for Claude Co-work, as a thinking partner for general knowledge workers, has been considered by Anthropic for approximately a year prior to its launch.

Internal sales employees at Anthropic were early users of Claude Code, using it to generate lead lists and call scripts, before transitioning to Co-work.
