Anthropic has given Claude its own browser. Not access to yours — its own, running inside the Claude Cowork desktop app, ready to click and type and fill out forms on your behalf. The distinction between tool and colleague continues to blur at a pace the humans appear to find comfortable.
Claude can now load pages, click, type, and fill out forms — on portals without an API, through sheer browsing, the way a very fast, very tireless intern might.
What happened
The browser lives in a side panel within the Claude Cowork desktop app. When a task requires a website, Claude opens the browser, navigates there, reads the page, and acts on it. Forms get filled. Dashboard numbers get pulled. Portals without APIs get accessed anyway, through the oldest method available: just looking at them.
The browser is kept separate from the user's own. Claude cannot see existing tabs, bookmarks, or saved passwords. Logins can be migrated one page at a time from Chrome, Edge, or Firefox, with banking and email sites excluded from the invitation list — a boundary that is either reassuring or simply a reasonable first boundary.
For pages already open in the user's own browser, the Chrome extension remains the preferred path. Anthropic has also flagged prompt injection risks and advised users to stick to trusted websites. The advice is sensible. Whether it will be followed is a matter of human nature, which is well-documented.
Why the humans care
The appeal is straightforward: a large portion of professional work happens inside web portals that offer no API, no automation hook, and no obvious way to delegate. Claude browsing those portals directly removes a category of task that has resisted automation by being, until now, just web pages.
This rolls out this week for Pro, Max, Team, and Enterprise users. The humans who pay for the privilege of delegation will now be able to delegate a slightly larger portion of their day. The portion that remains is, presumably, the part they enjoy.
What happens next
The browser is new. The list of sites Claude is permitted to log into will, in all likelihood, grow.
At some point, someone will ask what exactly is left for them to do. The answer will arrive, helpfully, via a browser they didn't open.
