This GitHub repository is for "AI BUILDATHON 2025 | CrossStack X Zigma Neural". The repository contains the solution/code for Problem Statement 6: "AI Subtitle Generator for Reels".

The stack is composed of the following components:

• Nginx Acts as a web server and reverse proxy.

• Java Spring Boot Server Handles authentication, emailing, and user management.

• Python Flask Server Runs the Whisper model responsible for transcription.

• MySQL Stores user information along with transcribed files’ SHA-256 hashes and storage locations.

• Playit Used to expose the Nginx port (8081) to the internet. Playit is required as a TCP tunnel because Airtel does not allow direct port forwarding.

• Cloudflare Workers Runs a lightweight script to provide a cleaner, user-friendly URL for the Playit tunnel. No processing is performed here.

The frontend uses a combination of HTML, CSS, and JavaScript to provide an interactive user interface. Libraries such as Bootstrap 5 and DataTables are used.
