👋 SignLangAI

SignLangAI is a Django-based web application that translates Russian text into videos with gestures of the Russian Sign Language (RSL), using pre-recorded gesture clips.
The project is designed for learning and communication with a limited set of gestures.

🚀 Core Features

• ✅ Translate phrases into a sequence of available gestures
• 🎥 Automatically merge gesture clips into a single video
• 💬 Chat history for authenticated users
• 🔐 User registration and authentication
• 🧠 GPT-4 for semantic phrase analysis and simplification to available gestures

📁 Tech Stack

• Backend: Django, MoviePy, GPT-4 (via gpt4free)
• Frontend: HTML + JavaScript + jQuery (via Django templates)
• Database: SQLite (default)
• Authentication: Django auth
• Video Storage:
  • media/gestures/ — individual gesture clips
  • media/outputs/ — generated videos

🧠 How Translation Works

1. User enters a phrase.
2. GPT-4 analyzes the phrase and generates a list of .mp4 gesture files.
3. The program merges these clips into a single video.
4. The final video is displayed in the chat window.

🧪 Example

Input:
Привет, как ты?

GPT-4 Output:
['привет.mp4', 'как.mp4', 'ты.mp4']

Result:
A stitched video with consecutive gestures 👋
