Claude Cowork now runs in Anthropic's Chrome extension sidebar

Anthropic has integrated Claude Cowork directly into the side panel of its Chrome extension, bringing skills and plugin support into the browser itself.

Why it matters: This extends Claude's agentic tooling beyond the desktop app and API into everyday browser use, putting it in more direct competition with browser-native AI assistants from Google and OpenAI. It fits Anthropic's broader push to meet users where they already work rather than requiring a separate app.
