GPT application

Hi freelancers,

I'm going to build brand new app based on AI.

Workflow:
- User upload documents for example pdf or excel sheets into app
- User ask natural language questions or use gpt prompt
- App (OpenAI api) returns results in wordings or graphic representation



Use-cases (examples)
- Business analyst uploading past revenue excel sheets and ask the application: what is the best selling product by region? And the application returns a result either in words or a graphical representation
- Finance manager upload past invoices (pdf) and ask questions on payment terms of different suppliers

Please mention how you implement this app.

Kind regards
Kurt
