It has never been easier to create a chatbot that can chat with your PDF documents.

Even with beginner-level Python skills and no prior UI/UX experience, you can achieve this feat.

Simply use @LangChainAI and @chainlit_io.

Here's how 👇

First, import the necessary libraries.

Although the list of imports for this chatbot may be quite long, don't let it discourage you.

The actual implementation is quite easy.

Next, define the essential variables.

These variables include the memory, the embedding, and your OpenAI API key.

Then, you need to create a factory function and ask the user to select a PDF file.

While still within the factory function, use Langchain to preprocess the PDF file and generate a vectorstore.

This vectorstore will be utilized for retrieval purposes later on.

Finally, (still inside of the factory function) create a Chain and return it.

This function should allow you to communicate with the documents and return a chain using the Chatbot UI.

The factory function ended up being lengthy, so it's worth revising.

Here's how it turned out:

And this is how you create a Chatbot to chat with your PDF files with a intuitive UI!
