A post on a large Korean online community recently went viral for claiming to reveal a tool that boosts office workers' productivity. Behind reactions like that, there is usually one real question: is there an actual tool that can take over repetitive desk work? There is an officially verifiable answer. On August 26, 2026, Anthropic made Claude in Chrome, a browser extension that reads a webpage and clicks, types, and fills forms on your behalf, generally available to all paid-plan users. This article walks through how to install it, what it can realistically automate, and how to use it safely, based on official documentation.

What you will be able to do after reading this
Following this guide, you can install Claude in Chrome and automate one real, repetitive web task (cleaning up email, checking a calendar, pulling data from a dashboard) within about 10 to 15 minutes.
What you need before you start
- Google Chrome on Windows or Mac (desktop only — other Chromium-based browsers and mobile are not supported)
- A Claude account on a paid plan: Pro, Max, Team, or Enterprise (not available on the free plan)
- If it is a work account, confirm your admin has enabled Claude in Chrome — Team and Enterprise admins can restrict it to an allowlist or blocklist of sites
Terms explained quickly
- Claude in Chrome — Anthropic's official extension that lets Claude read your Chrome browser screen and click, type, and fill forms on your behalf.
- Side panel — the assistant panel that opens on the right side of the browser once the extension is active; this is where you give tasks and watch progress.
- Approval mode — the setting that decides whether Claude checks with you before each action, or only pauses when it judges something risky and otherwise keeps going.
- Prompt injection — an attack where hidden malicious instructions are planted inside a webpage to trick the AI into acting differently from what you actually asked.
- Claude Cowork — a separate agent (a program that carries out tasks autonomously) that goes beyond the browser to organize files and create documents on your desktop.
What exactly is Claude in Chrome?
Claude in Chrome is Anthropic's official browser extension that reads a webpage directly and clicks, types, and fills forms for you. Before it became generally available (GA) on August 26, 2026, it ran as a pilot that required approval for every single action. Since GA, switching approval mode to automatic lets Claude chain multiple steps together. Its distinguishing feature is that it can act on internal dashboards, legacy systems, and vendor portals that have no direct API integration, using the same logged-in access a person would have.
Step by step: from install to your first automated task
- Open the Chrome Web Store — In Chrome, go to the Chrome Web Store and search for Claude. Click the install button shown on screen (officially labeled Add to Chrome). The exact wording can vary by browser language, so confirm it on your own screen.
- Sign in — After installing, sign in with your Claude account credentials. If your account is on the free plan, you may see an upgrade prompt at this point.
- Pin the extension — Click the puzzle-piece extensions icon, then click the pin icon next to Claude to keep it in your toolbar for one-click access to the side panel.
- Grant permissions — Approve the permissions the extension requests (reading tabs, running scripts, and similar).
- Choose an approval mode — In settings, pick either Automatically approve or Manually approve. If this is your first time, start with manual approval so you can see each action before it happens.
- Ask for your first task — Open the side panel and give one specific, narrow request, such as "clean up unread newsletters in my inbox."
Success looks like the side panel showing each step in order and ending with a completion message. If the panel stalls with no response, or keeps asking for approval without progressing, narrow the scope of your request and try again.
What kinds of work can it automate?
Claude in Chrome fits repetitive office tasks that happen inside a web browser. The use cases named in official materials include:
| Type of work | Example task |
|---|---|
| Data and analytics | Extract metrics from a web dashboard |
| File organization | Organize files in Google Drive |
| Calendar management | Check the calendar and prep for meetings |
| Research | Do competitive research and draft prep for a deck |
| Sales logging | Log call notes into a CRM |
| Clean up an inbox |
How is Claude in Chrome different from Claude Cowork?
Claude in Chrome works only inside the browser, while Claude Cowork also handles files and documents on your desktop. The Claude.ai chat window only answers questions and does not execute tasks itself. Claude in Chrome, by contrast, reads the webpage you are currently viewing and clicks and types on your behalf, and Claude Cowork goes a step further by organizing desktop files or directly creating documents such as Excel spreadsheets and PowerPoint decks. According to official information, Claude Cowork is available in the desktop app on paid plans, with web and mobile offered in beta. Exact availability can vary by plan and over time, so it is safest to confirm on screen.
What should you check before using it safely?
To use Claude in Chrome safely, avoid using it for sensitive work such as finance, legal, or medical matters, and actively monitor the approval mode and any warning signs. Official safety guidance explicitly says not to use it for managing bank accounts or investments, handling legal documents or contracts, processing medical or health information, work accounts with sensitive company data, or sites containing other people's personal information. Actions such as stock trading, bypassing CAPTCHAs, entering sensitive data, or scraping facial images are blocked outright, and organizations covered by HIPAA (the US health-privacy law) cannot use the extension at all.
Caution: the biggest risk is prompt injection. An attacker can hide malicious instructions inside a webpage you visit, tricking Claude into acting differently from what you asked. Anthropic describes three layers of defense: stronger resistance built into the model itself, probes that scan a page for risks before Claude acts on it, and a classifier that verifies each action matches your original request right before execution. In testing against professional red-teamers' strongest attacks, no successful attacks reached Sonnet 5 or Opus 5 with full safeguards enabled, and Fable 5 had a 0.3% attack success rate, according to official reporting (no separate figure for Fable 5.1, released September 2026, was confirmed as of this writing). That figure does not mean the risk is zero, though — if Claude suddenly shifts to unrelated topics, visits an unexpected site, or asks for sensitive information, stop the task immediately.
Common sticking points and fixes
- I'm on the free plan and can't install it — Claude in Chrome is not available on the free plan. You need to upgrade to Pro or higher.
- It doesn't show up in a non-Chrome browser — officially, other Chromium-based browsers and mobile apps are not supported. It only works in the Chrome desktop app.
- I want it to work with an Excel file on my computer, but it can't — Claude in Chrome only works with what is visible in the browser. Local file work requires the desktop app, Claude Cowork.
- Installation is blocked on my work account — on Team and Enterprise plans, admins manage site allowlists, blocklists, and access from Organization Settings. Check with your IT admin.
