Claude for
Chrome
A browser extension that lets Claude see your webpage, click buttons, fill forms, navigate tabs, and automate web-based tasks. Currently in beta.
Claude for Chrome lives as a collapsible side panel in your browser. While you browse, Claude can see the page you are on (via screenshots), understand what is on it, and take actions: clicking, typing, filling forms, switching tabs, navigating to new pages. It turns Claude from something you switch to into something that works alongside you in the browser.
How it works
Claude reads pages via screenshots and takes actions on your behalf.
The extension captures screenshots to understand page content. It can read text, identify buttons and form fields, and interact with them. It manages multiple tabs simultaneously and can navigate between pages as part of a multi-step workflow.
What you can do with it
Five use cases
Calendar management. "Find 30 minutes this week where I am free and Jo is free, then create a meeting called 'Migration sync' and invite both of us." Claude opens your calendar, checks availability across attendees, creates the event, and sends the invite.
Email drafting. "Draft a reply to the latest email from Priya. Reference the attachment she sent and ask whether the timeline in section 3 is still accurate." Claude reads the email thread, understands the context, and drafts a reply in the compose window. You review before sending.
Form completion. "Fill out the expense report form from this receipt image." Claude reads the receipt (via vision), identifies the fields on the expense form, and fills them in. Saves you the manual data entry on every line item.
Website testing. For developers using Claude Code: build in the terminal, verify in the browser, debug the results. Claude can test a feature you just deployed by navigating to the page, clicking through the workflow, and reporting what it sees.
Data extraction. "Go to this product page and extract the price, the specs, and the shipping time into a table." Claude navigates to the page, reads the content, and structures it into the format you asked for. Useful for competitive research, procurement comparisons, and market analysis.
Site-level permissions
Claude for Chrome uses a per-domain permission model. When Claude needs to access a new website, it asks for your permission first. You can grant or revoke access per domain at any time. This means you stay in control of which sites Claude can see and interact with.
Restricted sites
Certain categories of website are blocked entirely, regardless of permissions:
- Financial services and investment platforms
- Cryptocurrency exchanges
- Adult content
- Sites involving sensitive personal data
Anthropic explicitly recommends against using Claude for Chrome on any site involving financial, legal, or medical information, even if it is not in the blocked list. Use judgement.
Who can use it
| Plan | Access | Model |
|---|---|---|

| Pro | Coming soon | Haiku 4.5 only when available |
| Team / Enterprise | Yes (beta) | Any model |

Safety considerations
Read this before using Claude for Chrome
- Prompt injection is a real risk. Malicious instructions hidden in webpages can attempt to trick Claude into unintended actions. Anthropic reports about a 1% attack success rate against adaptive attackers. That is low but not zero, and it means you should not rely on Claude for Chrome for high-stakes operations.
- JavaScript access. When enabled, Claude has access to browser sessions, stored data, and login credentials on permitted sites. If compromised through prompt injection, this could theoretically enable credential theft. Keep permissions narrow.
- Action confirmations. Some high-risk actions require your explicit approval before Claude executes them. These prompts exist for a reason. Read them.
- Not for sensitive operations. Do not use Claude for Chrome to interact with banking, investment, legal, or medical systems. Even if the site is not on the blocked list.
Getting started
Install from the Chrome Web Store. Search for "Claude" or visit the link from claude.com/claude-for-chrome. Install and sign in with your Claude account.
Grant initial permissions. The extension requests permissions to access your browser tabs and interact with pages. Review and accept.
Open the side panel. Click the Claude icon in your browser toolbar to open the panel. It sits alongside your page and stays visible as you browse.
Start with something low-stakes. "What is on this page?" or "Find the contact email on this site" are good first tasks. Build up to form filling and multi-step workflows once you trust the interaction model.
Claude for Chrome is the most experimental tool in this section. It is genuinely powerful for web automation, but it comes with real security considerations. Start small, keep permissions narrow, and do not use it on sensitive sites.
