PDF Summarizer - Node.js

This is a Node.js application that allows users to upload PDF files and summarize the content of the PDF file. The application uses Groq to run the large language model (LLM) inferences that power the PDF summarization. It demonstrates the ability to easily use LLMs to implement intelligent natural language workflows.
