I’m new to langchain and AI , currently developing a PDFRAG app .

Currently , I’m able to upload a PDF , ask questions from it , the response is streamed back to me .

This is working fine .

Now , I want ChatGPT like functionality where the title of the response is larger in font size and bold and the subtitle / the text is smaller in font size and normal in style .

This is my app response to a query where I ask the model to generate a title and subtitle .

And this is AIPDF’s response .

I want my response like AIPDF .

What do I need to do ? I’m using Langchain and Streamlit to develop my application .

Searched streamlit and langchain docs.
