Overview
When a task involves a website, Cowork opens a built-in browser where Claude navigates, clicks and fills forms while the user watches.
Workflow
Suggested implementation: Use Claude Cowork's built-in side-panel browser to navigate websites, fetch data, and fill forms without installing extensions. The agent operates in a separate browser instance while the user monitors the process visually. Human role involves watching the execution and verifying outputs before final submission.
Reported result
Actual outcomes are unknown as the source link returned a 403 error and no performance metrics were provided in the available text. A pricing comparison workflow was mentioned as an example, but success rates or time savings are not documented. Proposed acceptance check: Measure time saved versus manual entry on a test form and verify 100% field accuracy before submission.
Human role
The original post does not say how a person stayed involved.
Limitations
The feature is isolated from the user's normal browser by default, requiring opt-in to import Chrome logins. It is currently available to paid desktop users. Source reliability is low due to the inaccessible original post. Human approval is required for any action that submits data or spends money.
Try it
Act as a user instructing an agent to test Claude Cowork's browser capabilities. Context: I need to compare pricing for [Product Name] across [Website 1] and [Website 2]. Inputs: Target URLs [URL_1], [URL_2] and search keywords [Keyword]. Steps: 1. Open the side-panel browser in Cowork. 2. Navigate to [URL_1] and extract the price for [Product Name]. 3. Navigate to [URL_2] and extract the price. 4. Fill a test form on [Test Site URL] with dummy data [Name: Test, Email: test@example.com]. 5. Stop before submitting. Output: A table comparing prices and a screenshot of the filled form. Quality Check: Verify the extracted prices match the visible page text. Error Handling: If a site blocks the browser, report the error and do not attempt to bypass it. Safeguards: Do not submit any forms or make purchases. Ask me for confirmation before proceeding to any live transaction. First, perform a dry run on a public, non-interactive page to confirm navigation works.
