Claude for Chrome
Claude for Chrome installs Claude as a browser extension: it reads an open page, clicks, fills in forms and chains actions across multiple tabs on the user's behalf, with no script or code required. Launched as a restricted pilot to 1,000 Max plan users in August 2025, it has since opened up to all paid plans (Pro, Max, Team, Enterprise).
Key advantages
- No technical skills required, unlike a library such as Browser Use
- Natively integrated into the Claude ecosystem, no separate API key to manage
- Admin controls (site allowlists/blocklists) for Team and Enterprise accounts
Who it's for, and why
Claude users who want to delegate repetitive web browsing tasks (research, form filling, monitoring) without writing code or using a library like Browser Use.
- Researching and summarizing information across several open tabs
- Assisted filling of repetitive web forms
- Automating online administrative tasks without a script
Getting started
- 1Install the extension from the Chrome Web Store (search for "Claude"), available on Google Chrome desktop only.
- 2Sign in with a Claude account on a paid plan (Pro, Max, Team or Enterprise): the free plan doesn't include access.
- 3Pin the extension via Chrome's puzzle-piece icon, then grant the requested permissions.
- 4Read the official "Use Claude in Chrome safely" page before a first use on sensitive sites.
Things to watch out for
- Anthropic's own official warning: despite reinforced safety classifiers, the extension is still described as "risky" as-is, particularly against prompt injection attempts from a compromised web page.
- A real vulnerability ("ShadowPrompt", a zero-click prompt injection) was discovered and fixed via an official patch (version 1.0.41, strict origin check against claude.ai) in late 2025: a reminder that this kind of extension is an active attack surface, not just a gadget.
- Restricted to Google Chrome desktop: no compatibility with Edge, Brave, Arc or mobile versions.
- Requires a paid Claude plan (Pro, Max, Team or Enterprise): no access via the free plan.
Frequently asked questions
Is Claude for Chrome free?
The extension installs for free from the Chrome Web Store, but using it requires a Claude account on a paid plan (Pro, Max, Team or Enterprise): the free plan doesn't include access.
Is it risky to let Claude act directly inside my browser?
Anthropic states it plainly in its own documentation: despite reinforced classifiers against prompt injection, usage remains risky. A real vulnerability (ShadowPrompt) was in fact discovered and fixed in late 2025, which confirms that caution is still warranted, especially on sensitive sites (banking, work email).
Does it work on Edge, Brave or mobile?
No, the extension is strictly limited to Google Chrome on desktop. No mobile version or compatibility with other Chromium-based browsers is offered to date.
How is it different from Browser Use, the other browser-automation tool in this list?
Browser Use is a code library to integrate into your own Python scripts, while Claude for Chrome is a finished product, installable without writing a line of code, but limited to the Claude ecosystem and to Chrome.
