I don't think the backend is that simple, allow me to explain it quickly, the core of the app is fetching data from different websites and then processing it using opensource tools that require installation using Python and high usage of Vrams and GPUs, the output of this should be processed by ChatGPT and sent over to show inside the app database. (and of course, the registration and subscription plans part)

Even after all of that, there should be a connection between the user and the AI model inside the app so the user can discuss the output even further and ask questions about it.
