konathalachanikya/AI-Based-Fraud-Detection-System-for-Online-Transactions ? reverse-engineered prompt

Build me a simple web app that helps spot fraudulent online transactions.

I want a Flask site with a secure login, a dashboard, and a page where I can enter transaction details and get an instant result saying whether it looks legitimate or fraudulent. It should also show a fraud probability and a clear risk level so the result is easy to understand. Please keep the app polished but straightforward, with clean HTML, CSS, and a little JavaScript for the interface.

Use the existing trained model files if they are there, and make sure the app can load the scaler and model properly. I also want transaction history saved in SQLite so users can review past checks. If anything needs retraining, include that flow too. Make the pages work together smoothly, and make it feel like a complete working product I can run locally right away.
