Verified — and this shipped for real on Aug 27, not just a leak. Here's the short post: Claude Desktop just got its own browser — and Cowork can drive it The leak from two weeks ago just shipped. This one actually changes what your agent can do 👇 What's live: a built-in browser inside the Claude Desktop app that Cowork can use directly. No Chrome extension, no permissions dialog, no dependency on Google. The key details: → It's isolated — runs separately from your personal browser. Claude isn't touching your everyday Chrome profile. → Login handled two ways: manually, or import cookies site by site. Banking, email, and SSO sites stay UNCHECKED by default. Smart default. → The browser lives in the desktop app, so it needs to stay open — but you can steer the session from web or mobile while it runs. → It opens automatically when a task needs it. You don't launch it, Claude does. My take: This is the "super app" play. Anthropic is quietly making Claude the one window you never close — chat, agent, files, and now web, all in one place. OpenAI shipped a cloud browser for ChatGPT Work days earlier. Everyone's converging on the same shape. But the interesting bit is the isolation choice. By keeping the browser separate from your real profile, Anthropic traded convenience for safety — Claude can't act inside your logged-in Notion or Gmail unless you deliberately import that cookie. Given that browser agents are a live prompt-injection target, that's the right call, even though it means more setup. For builders and operators: This unlocks web automation for tools with no API. Vendor portals, internal dashboards, Search Console, lead research, anything that only exists behind a login. Cowork can now log in and work there as part of a scheduled task. That's a real category of client work that just got automatable. Think invoice collection across vendor portals, weekly reporting pulls, competitor monitoring — jobs that used to need a human clicking or a fragile scraper.
