# Chat with PDF and Images 📄🤖

A Streamlit-based app that enables users to upload PDF documents or images, extracts text from them, and allows interactive chat about the contents. This app uses Google Generative AI (Gemini API) to answer questions based on the uploaded documents.

## Features
- Upload PDF or Image (PNG, JPG, JPEG) files.
- Extract text from PDF documents or images.
- Ask questions related to the uploaded content.
- Interactive chat interface with animated styling.
- Simple, clean UI with custom CSS styles.

## Tech Stack
- **Streamlit**: For creating an interactive UI.
- **PyPDF2**: To extract text from PDF files.
- **Tesseract OCR**: To extract text from images.
- **Google Generative AI (Gemini API)**: For generating answers based on extracted text.
- **Pillow**: For image processing.

## Getting Started

### Prerequisites
1. Python 3.7+
2. [Tesseract OCR](https://github.com/tesseract-ocr/tesseract) installed (ensure the path to `tesseract.exe` is correct).
3. Google Generative AI (Gemini API) key.
