Anthropic is folding Cowork, its agentic work environment, into the default Claude chat on web, desktop, and mobile for Pro and Max plans, with Claude Docs and Claude Slides in beta and Claude Design available inside conversations and standalone.
Anthropic announced on August 26, 2026 that its official Chrome extension, Claude in Chrome, reached general availability for paid Claude plan users. The extension had been in beta. It lets Claude operate autonomously in the browser without requiring approval for each action, and it works on sites that do not integrate with Claude by using existing login information to view pages, read and write text, click links, navigate between pages, and fill out forms. Anthropic says probes that scan page content before Claude loads it, plus a safety classifier that checks each action against user instructions, reduced the success rate of prompt injection attacks to 0 percent in model 5. The extension installs from the Chrome Web Store.
Coverage of the extension also described a built-in browser for Claude Cowork that does not require the extension, separating web tasks from the user's personal browser. That browser sits inside Cowork, which Anthropic positioned as the agentic work environment for its Claude assistant. The two products addressed different setups: the extension for users who want Claude to act inside the browser they already use, and the Cowork browser for users who want web tasks handled off their personal browser.
On September 17, 2026, Anthropic said it will integrate Cowork into the default chat, so users no longer choose between chat and the agent workspace. Anthropic said it heard a complaint about not knowing which workspace to use. The change rolls out over several weeks to the Claude apps on web, desktop, and mobile for Pro and Max plans. Claude Docs and Claude Slides are in beta, and Claude Design is available inside conversations as well as standalone.

Anthropic announced on August 26, 2026, that its official Chrome extension, Claude in Chrome, is now generally available to paid Claude plan users. Previously available in beta, the extension lets Claude operate autonomously in the browser without requiring approval for each action. Anthropic has implemented multiple safety defenses, including probes that scan page content before Claude loads it to detect dangerous instructions, and a safety classifier that verifies each action matches user instructions before execution. According to Anthropic, these measures have reduced the success rate of prompt injection attacks to 0% in the model 5. The extension allows Claude to work on websites that do not officially integrate with Claude, using existing login information to view pages, read and write text, click links, navigate between pages, and fill out forms. Claude in Chrome can be installed from the Chrome Web Store. At the time of writing, its store rating was 2.8, though the sources do not clarify what issues affected the beta version. The extension addresses the gap between tools that integrate with Claude and those that do not, such as internal dashboards, legacy systems, and vendor portals.
