Custom GPT Learning by PDF Examples

Hello everyone,

I do want to build a custom gpt to look for specific papers in pdf files.
For instance, I do have a pdf file that includes various papers like: certificates, declarations or statements.

I want GPT to find those papers and generate a table with its name and the page where it found it.

My problem: I want to upload a similar pdf file that contains also certificates, declarations or statements, and identify those papers and I want to identify those papers myself so GPT can learn how I ve identified them.

Do you have any idea how to implement a pdf file as a model?

Thank you.
