Summary
The video demonstrates Claude Cowork operating within a Google Chrome side panel to automate a multi-tab financial close workflow.
The demonstration starts with a Chrome browser window displaying multiple open tabs containing monthly billing statements and invoices for a business named Plants Shop. These include portals and invoices from ABC Property Management LLC, Municipal Utility District 42, Print Co 123, XYZ Courier Co, a software company, Snack Vendor LLC, and Waste Services Inc. The user launches Claude by clicking its icon in the Chrome toolbar, which opens a side panel chat interface running the Opus 5 High model.
The user enters the prompt asking Claude to run the month-end close across the open tabs, pull each invoice, and place the details into the monthly report. Claude begins execution by reading the open tabs to assess the required information. The interface cycles through each individual browser tab, scanning statements such as past due print invoices, courier delivery charges, and recurring utility bills.
Once tab processing completes, Claude summarizes the financial findings. It reports a July total of $10,017.80 verified programmatically, showing an increase of $2,605.53 compared to June total of $7,412.27. Claude explains the variance by noting an annual software renewal of $1,788.00, courier charges increasing 49 percent to $918.30 due to volume growth, and utility bills increasing 42 percent to $612.40 from seasonal cooling.
Claude also highlights specific action items, noting a past-due Print Co invoice of $526.91 with a potential late fee, confirming auto-pay status on the software renewal, and suggesting verification for an insurance payment. Finally, Claude generates a linked Google Drive spreadsheet titled Plants shop monthly accruals, displaying an organized invoice log itemizing invoice numbers, vendors, issue dates, due dates, statuses, and payment amounts totaling $10,017.80.
Chrome side panel interface
The Claude extension opens directly within Google Chrome as a dedicated side panel alongside existing browser tabs. Users can type natural language instructions into the chat box while Claude accesses open tabs across the active browsing session.
Automated multi-tab data extraction
In the demonstration, Claude is prompted to run a month-end close by pulling data from multiple open invoice tabs. The tool navigates through tabs for property management, printing services, courier deliveries, software subscriptions, office snacks, utilities, and waste services to capture key figures.
Financial summary and spreadsheet output
After reviewing all invoices, Claude provides a detailed textual breakdown comparing current figures to prior month figures. It flags past due bills, annual subscription renewals, and seasonal cost spikes before exporting the structured data into an organized invoice log spreadsheet.
