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.

How They Work
BrowserOS Cowork
Claude Cowork
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
Claude Cowork runs in an isolated virtual machine on your desktop via the Claude Desktop app.
- Runs in a secure VM, isolated from your main system

- ~4 connectors (Google Drive, Gmail, DocuSign, FactSet)

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

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.
