Please validate my idea.

Hi, I am Preet and I am working on a website where students can feed raw information like textbooks, PDFs, web pages, raw text, documents, youtube videos, etc.

And then you can chat, generate quizes, get summary on a particular topic, generate PPT, etc.

Unlike chatGPT knowledge will only come from the data you previously provided.

Will it be useful to you all or should I drop this idea?
