themuneebstuff/Invoice-AI ? reverse-engineered prompt

Build me a clean invoice AI web app front end in a single page that helps someone upload or enter invoice details, review them, and see the extracted summary in a simple dashboard.

I want it to feel modern and easy to use, with a place to add invoice number, date, vendor, line items, totals, and a clear section for AI extracted results. Include a file upload area, a preview panel, and buttons to process, edit, and download or save the invoice data. Make it responsive and polished so it works well on desktop and mobile.

Keep the experience simple and practical, like something a small business owner could actually use right away. If you need any current browser or UI docs, look them up online.
