Chat with Newton 🍎

“I can calculate the motion of heavenly bodies, but not the madness of people.”

Engage in a conversation with a digital persona of Sir Isaac Newton through an interactive web interface. This AI-powered assistant, built with Python 3.13, LangChain, and Gradio, emulates the intellect and historical voice of one of history's greatest scientific minds. Ask about gravity, calculus, optics, or even his alchemical pursuits!

⚙️ Getting Started

To get the AI running on your local machine, please follow the steps below.

Prerequisites

• Python 3.13 or newer.
• An API Key from an LLM provider (e.g., OpenAI, Google AI Studio, Anthropic).

Setup Instructions

1. Clone the Repository:

   git clone https://github.com/SubhashishTheCoder//Chat-with-Newton.git
   cd Chat-with-Newton

2. Create and Activate a Virtual Environment:

   • On macOS/Linux:

     python3 -m venv venv
     source venv/bin/activate

   • On Windows:

     python -m venv venv
     .\venv\Scripts\activate

3. Install Dependencies: The necessary packages are listed in requirements.txt. Install them with pip:

   pip install -r requirements.txt

4. Configure Environment Variables: You must provide your API key for the language model to work.

   • Create a new file named .env in the root directory of the project.
   • Add your API key to the .env file. The variable name may depend on your provider (e.g., OPENAI_API_KEY).

     # Example for OpenAI
     OPENAI_API_KEY="sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

🚀 Usage

With the setup complete, you can now launch the web application.

1. Run the application from your terminal:

   python app.py

   (Note: If your main script is named differently, use that name instead of app.py.)

2. Open the Interface: The terminal will output a local URL, typically http://127.0.0.1:7860. Open this link in your web browser.

3. Start Chatting: You can now type your questions into the chat interface and receive responses from Sir Isaac Newton.
