# 💡 DevDeCode: Explain Code with LLM

DevDeCode is a simple but powerful code explanation tool powered by **Google's Gemma 2B** and **LangChain**. Paste any code snippet (Java, Python, etc.), and get a natural-language explanation to help you understand what it does.

> 🧠 Built using Hugging Face Transformers, LangChain, and Gradio.

---

## 🚀 Features

- 📜 Explain small code snippets using LLM
- 🧩 Supports languages like Java, Python (others can be added)
- 🌐 Web-based interface via Gradio
- 🔄 Can be extended with memory & history tracking

## 🧪 How to Use

Just paste a code snippet into the textbox and click submit. The model will explain what the code does.

⚠️ **Note:** The response time may vary depending on your GPU and input length. Model is gated — ensure you're authenticated.

---

## 🧩 Example Prompt

public class Factorial {
public static int factorial(int n) {
if (n <= 1) return 1;
return n * factorial(n - 1);
}
}


👆 Get a clear explanation of recursion, factorial logic, and base conditions.

## 🔐 Hugging Face Token

This model uses a gated Google Gemma 2B model. Make sure your Hugging Face token is set via:

- Hugging Face Spaces secrets (`HF_TOKEN`)
- Or via `huggingface-cli login` locally.

## 🧠 Coming Soon

- Memory / Chat history support
- Upload files for batch code analysis
- Multi-language explanation support
