mauryarahul007/gmail-expense-tracker — reverse-engineered prompt

Build me a simple web app that connects to my Gmail and turns purchase or receipt emails into an expense tracker.

I want it to scan emails that look like orders, bills, subscriptions, or payment confirmations, pull out useful details like merchant, date, amount, and maybe a category, then save everything so I can review it in one place. Give me a clean dashboard where I can see total spending, recent transactions, monthly summaries, and basic filters like date range or category. It should also let me correct anything the email parser gets wrong, mark items as ignored, and avoid duplicate entries.

Please make it feel usable end to end, with a frontend and backend, basic login or Gmail authorization, and clear setup steps so I can run it locally. If some email formats are messy, do a reasonable best effort and make the data editable. Keep the UI simple and practical. You can look up current Gmail integration docs if needed.
