abdulhayykhan/AsaanBill-AI ? reverse-engineered prompt

Build me a web app called AsaanBill AI that helps people in Pakistan understand and audit their utility bills, like electricity, gas, and water.

I want users to upload a bill image or PDF, then the app should pull out the important details, check whether the math adds up, and show a clear breakdown of the charges in simple, conversational language. If the bill total does not match the charges, highlight the mismatch and explain what looks off. Also include a few practical money saving tips based on the bill.

Please make it save past bills so users can see their monthly history and trends over time, like total amount and units used. The app should have a clean frontend for uploads and charts, plus a backend API that handles the AI analysis and stores records in a PostgreSQL database. Use Gemini 2.5 Flash for the AI part, and if you need to look up current docs online, go ahead.
