Both BrowserOS Cowork and Claude Cowork let an AI agent work with your local files autonomously. You describe a task, step away, and come back to completed work. They share a similar file toolkit under the hood. The key difference is what else each product can do. BrowserOS Cowork runs inside a real browser with full web access and 40+ app integrations. Claude Cowork runs inside an isolated VM with professional document generation. This page compares both products so you can decide which fits your workflow.

Feature Comparison

​
File Operations

Both products provide a comparable set of file tools. You can read, write, edit, search, and organize files in both. This is table-stakes for both products.
The file tools are largely equivalent. The real differentiator is what else each product can do beyond file operations.

​
Working with the Web

This is the biggest difference. BrowserOS Cowork runs inside a real browser with your existing logins and sessions. Claude Cowork has no browser access. If your task involves anything on the web, whether that’s researching, filling out forms, grabbing content from a site, or checking on a web app, you need BrowserOS.

​
Connected Apps

BrowserOS connects to 40+ services directly. Claude Cowork has a handful of connectors.

​
Document Generation

Claude Cowork has an edge when it comes to creating polished office documents.

​
How They Work

BrowserOS Cowork runs inside the browser. The agent has access to your real browser session (cookies, logins, extensions) and a sandboxed folder on your computer.
  • Works in your real browser with your existing logins
  • File access sandboxed to the folder you select
  • 40+ app integrations via OAuth
  • Connect from any AI tool (Claude Code, Gemini CLI, Cursor, etc.)
  • Uses whatever AI model you choose

​
Where Claude Cowork Shines

  • Professional documents: Create Excel spreadsheets with working formulas, PowerPoint presentations, and formatted Word documents
  • Parallel subtasks: Automatically breaks complex work into smaller tasks that run at the same time
  • Stronger isolation: Runs in a full virtual machine, giving you OS-level separation from your main system
  • Zero setup: Works out of the box in the Claude Desktop app with pre-installed tools and languages

​
Where BrowserOS Cowork Shines

  • Full browser access: Navigate websites, fill forms, click buttons, take screenshots, and extract content from any page. Claude Cowork cannot touch the web.
  • Your real logins: Because it runs in your actual browser, the agent can access sites where you’re already logged in: dashboards, internal tools, social media, banking portals, anything.
  • 40+ app integrations: Gmail, Slack, GitHub, Calendar, Notion, Linear, Figma, Salesforce, and more. All accessible in the same session as your file work. Claude Cowork has about 4 connectors.
  • Pick your AI model: Use Claude, GPT-5, Gemini, Kimi K2.5, or a local model. Claude Cowork only works with Claude.
  • Full internet access: Your agent can visit any website. Claude Cowork’s VM is restricted to a short list of allowed sites.
  • Free: BrowserOS is free. Just bring your own AI API key. Claude Cowork requires a paid Claude subscription.

​
Summary

Both products handle file operations equally well. The choice comes down to what else you need. If your work touches the web, connected apps, or you want to choose your own AI model, BrowserOS Cowork gives you that. If you need polished office documents and prefer a fully isolated desktop experience, Claude Cowork is a good fit.
