yashwanthchikki/datawise ? reverse-engineered prompt

Build me a simple web app where I can upload CSV, Excel, or JSON files and then ask questions about the data in plain English, without needing SQL.

I want the app to clean and save the data, show a quick preview, and let me chat with the dataset like a conversation, so follow up questions still make sense. It should also generate useful insights automatically, like trends, outliers, correlations, and short recommendations that I can actually understand.

Please add clear charts for the answers, with a few different chart options and easy export. I also want professional looking reports I can download as PDF and Excel, with summaries, stats, and charts included. Use a database so uploaded files and query history are saved, and make the experience feel polished and easy to use. If you need to check current docs for anything, go ahead and look them up online.
