Chat With PDFs

Chat with your PDF files for free, using Langchain, Groq, Chroma vector store, and Jina AI embeddings. This repository contains a simple Python implementation of the RAG (Retrieval-Augmented-Generation) system. The RAG model is used to retrieve relevant chunks of the user PDF file based on user queries and provide informative responses.

Installation

Follow these steps:

• Clone the repository

git clone https://github.com/S4mpl3r/chat-with-pdf.git

• Create a virtual environment and activate it (optional, but highly recommended).

python -m venv .venv
   Windows: .venv\Scripts\activate
   Linux: source .venv/bin/activate

• Install required packages:

python -m pip install -r requirements.txt

• Create a .env file in the root of the project and populate it with the following keys. You'll need to obtain your api keys:

JINAAPIKEY=<YOUR KEY>
   GROQAPIKEY=<YOUR KEY>
   HF_TOKEN=<YOUR TOKEN>
   HF_HOME=<PATH TO STORE HUGGINGFACE MODEL>

• Run the program:

python main.py

Configuration

You can customize the behavior of the system by modifying the constants and parameters in the main.py file:

• EMBEDMODELNAME: Specify the name of the Jina embedding model to be used.
• LLMNAME: Specify the name of the language model (Refer to Groq for the list of available models).
• LLM_TEMPERATURE: Set the temperature parameter for the language model.
• CHUNK_SIZE: Specify the maximum chunk size allowed by the embedding model.
• DOCUMENT_DIR: Specify the directory where PDF documents are stored.
• VECTORSTOREDIR: Specify the directory where vector embeddings are stored.
• COLLECTION_NAME: Specify the name of the collection for the chroma vector store.
