Add the possibility to upload PDFs in the front part of the application to read it

[maxime-dlabai]

Create on the front end the possibility to upload a PDF file for example with the following procedure:

• Parsing the file to read it
• Split content to respect "limit" of tokens for model to send.
• To be able to make queries on the elements of the document from the prompt.

(Of course it's not critical but it would really be a plus on the front)

Yeah that would be super useful agreed! I think we need to implement a LangChain integration (see #4) in order to do this the easy way and not reinvent the wheel.

I will try to work on this in the near future

I'll look into the LangChain integration on my end, if I can help.

For sure, feel free to share your findings

The models usually can't actually read very much without forgetting what they already read. You might be able to upload a page or two, but for that much you could probably copy and paste just as easily.
