Claude in Chrome
A helping hand across all your tabs
Claude in Chrome reads the page you’re signed in to, then clicks, types, and fills forms while you decide what happens next.

No more copying, pasting, and switching tabs.
From browser research to finished deliverables
Pair Claude in Chrome with Claude Cowork to turn web research into polished content. Chrome navigates and gathers information, Claude Cowork produces Excel models, comparison decks, and reports without having to copy and paste.
Works with Claude Code
Connect development workflows to Chrome for a partner that tests and iterates with you.
Uses your everyday tools
Bring Claude into your workflow to make apps work better, without leaving the browser.
Runs tasks in the background
Start a workflow and move on. Claude completes tasks while you focus elsewhere.
Pull metrics from analytics dashboards
Claude can navigate your analytics dashboard, extract the numbers you need, and compile them into a summary. No exports, no tab-switching, no manual copying.
Organize files in Google Drive
Claude can sort through your Drive, create a folder structure, move files where they belong, and flag duplicates and old files for you to review. You approve the changes instead of doing the sorting yourself.
Prepare and plan from your calendar
Claude can read your calendar, pull context from email threads, flag which meetings you need to prepare for, and book rooms if they’re missing. Run it every evening and start each day knowing what's coming.
Research competitors, get a comparison deck
Claude in Chrome visits competitor sites and pulls pricing, features, and positioning. Claude Cowork compiles everything into a formatted PowerPoint ready for your next strategy meeting.
Log sales calls to your CRM
Claude can read your calendar, match attendees to Salesforce contacts, and draft activity logs for each call. You add notes and approve before anything gets created.
Clean up promotional emails
Claude can scan through your inbox, identify marketing emails, newsletters, and automated notifications, then present them as a list for you to review before deleting in bulk.
Reach the web that has no API
Access internal tools, legacy portals, admin consoles, and invoice systems. Claude works with the logins you have, on the tab in front of you. Drag more tabs into Claude’s tab group and Claude works across all of them.
Your whole setup, in the side panel
The side panel now runs a full Claude Cowork session. The skills, plugins, and connectors you've already built are there, with nothing to set up in the browser.
Your session follows you
Every conversation saves to your history. Sessions live with your account, not the machine, so you can start in Chrome and pick it up on desktop or mobile without needing to re-explain. A skill you save in the panel runs from any surface too.
Three ways to access the extension
Access Claude in Chrome through the side panel when the work is on the page in front of you and nothing else needs to be open, in Claude Cowork when the browser is one step in a longer job, or in Claude Code when you’re building the site you’re testing.
Hidden instructions on a page can try to redirect Claude’s actions. Though Claude in Chrome has built-in defenses that have been tested against real attacks, we recommend the habits below as a best practice.
What we built
Automatically approve actions with guardrails
If you choose to, Claude can work through a task without asking you to approve each step. Before it acts on a page, a separate safety check reviews the action for risk and for instructions hidden by the site. It will surface to you if anything seems off.
Give permissions, site by site
If you prefer more control, switch to Permissions Mode. You grant access one site at a time. Claude can't reach anything you haven't approved.
Claude stops before taking sensitive actions
Purchases, financial actions, and other one-way doors wait for you.
Admins decide for the organization
On Team and Enterprise, admins turn the extension on or off org-wide and set site allowlists and blocklists.
What we recommend
Don’t use on sensitive workflows
Skip banking, health records, and anything with credentials you wouldn't share. Start with workflows you already know well.
Review Claude prompts
Claude asks before financial, personal, or work-critical actions. Review its prompts carefully.
Watch for unusual behavior
Some sites hide instructions that override yours. Our classifiers provide a defense, but if Claude acts unexpectedly, pause and review.
Tell us when something looks wrong
Report issues through the feedback options. It’s how we catch attacks we haven’t seen.
Claude Cowork now includes its own built-in browser — nothing to install, and fully separate from your own browsing. If you're new to browser use, Claude uses the built-in browser by default. If you already use Claude in Chrome, that stays your default and Claude keeps working in your browser, where you're already signed in. Switch anytime in Settings → Cowork → Preferred browser.
Avoid financial transactions, password management, or anything involving sensitive personal data. Start with trusted sites and familiar workflows where you're comfortable having Claude take actions. Make sure your use complies with our acceptable use policy. Learn more.
Browser AI faces unique security risks, like prompt injection attacks, where malicious actors might try to trick Claude into unintended actions, such as sharing your bank information or deleting important files. While we’ve implemented protections, they aren’t foolproof. Attack vectors are constantly evolving and Claude may hallucinate, leading to actions that you did not intend. We’ve shared our testing results, including possible attack scenarios, so you can make informed decisions, and strongly encourage you to read about the risks (opens in new tab) before using this product.

On its own, Claude in Chrome helps you navigate, extract information, and take actions in your browser. Paired with Claude Cowork, Chrome becomes the research layer for larger tasks. Claude gathers information from the web, then Claude Cowork produces finished files like Excel workbooks, PowerPoint decks, and formatted reports. Both remain available in Cowork. Claude uses the built-in browser by default unless you already use Claude in Chrome; you can pick your default in Settings → Cowork → Preferred browser.
