PROGRAMIK9/OpenAudit ? reverse-engineered prompt

Build me an AI powered expense audit app where users can sign up, log in, and upload receipt files like PDF, JPG, or PNG. I want the app to read each receipt, pull out the store name, amount, date, category, and item details, then show the results in a clean dashboard with totals and a list of all uploaded receipts. It should also flag anything suspicious, like duplicate receipts, missing information, or unusually large amounts, so users can review them easily.

Add a tax calculator for Indian tax rules that compares old and new regimes, includes common deductions like 80C, HRA, and standard deduction, and shows potential savings clearly. Include an admin area, protected pages, and basic profile management. Make it look modern and easy to use, with a simple front end and a backend that stores users, receipts, and tax history. If anything needs current library or API details, look them up online first.
