# Chat with your Documents

A powerful document interaction application that enables natural language conversations with your documents using LangChain and Ollama. This application supports multiple document formats and maintains persistent chat history for seamless document interactions.

## 🌟 Features

- **Multi-Format Document Support**
  - PDF files (.pdf)
  - Word documents (.doc, .docx)
  - PowerPoint presentations (.ppt, .pptx)
  - Excel spreadsheets (.xls, .xlsx)

- **Intelligent Document Processing**
  - Advanced text chunking with language-aware splitting
  - Efficient vector storage using FAISS
  - Multilingual support with paraphrase-multilingual-MiniLM-L12-v2 embeddings

- **Interactive Chat Interface**
  - User-friendly Gradio web interface
  - Persistent chat history across sessions
  - Context-aware responses using ConversationalRetrievalChain

- **Document Management**
  - Easy document upload and processing
  - Quick switching between documents
  - Historical chat retrieval for each document

## 🚀 Getting Started

### Prerequisites

- Python 3.11 or higher
- Ollama installed and running locally
- Virtual environment (recommended)
