Creating a PDF reader chatbot using Langchain and OpenAI is now easier than ever, thanks to the power of Large Language Models (LLMs) like GPT 3.5, Llama 2, and Claude. In the past, only data scientists could build AI systems for tasks like recommendations, fuzzy search, OCR, and more. But with accessible LLMs, the barrier to entry has significantly lowered.

In this article, we will be creating a pdf reader chatbot using open ai and langchain. We will be uploading the Budget of India 2023–24 and ask questions to it.

Here is the link to the budget pdf
