Claude (search, Claude in Chrome and hosted browsing): what it does and what it costs
In short
Anthropic's Claude reads sites through three robots, and acts for a user inside Chrome through an extension included with the Pro plan at 17 US dollars a month billed annually. A hosted browser announces itself as Claude-Agent, and a site's own settings decide whether those visits may complete tasks.

What it does not do
- Claude in Chrome does not visit as one of Anthropic's crawlers; it works inside the user's own signed-in Chrome session.
- Anthropic does not treat a Claude-Agent User-Agent alone as proof; its help center tells site owners to check the published IP list.
