ravindran-dev/smartspend ? reverse-engineered prompt

Build me a smart expense tracker web app that lets users upload receipt or bill images and automatically pulls out the vendor, date, total amount, and line items, then suggests an expense category for it.

I want a clean dashboard where people can see their spending trends, simple charts, recent expenses, and category summaries. Let users review the extracted info, fix anything that looks wrong, and save it into their expense history. It should also support exporting reports in PDF or CSV, and show a confidence score when the app is not sure about a result.

Use a modern React frontend and a Python backend with OCR and machine learning for the extraction and categorization flow. Keep the UI polished and easy to use, with a clear upload area and responsive layout. If anything is missing or there are better current docs online for the OCR or model setup, look them up and follow the best approach.
