System Requirements Document for happy-transform

Introduction

This document outlines the requirements for transforming the existing single-file HTML SEO spintax tool into a fully functional, production-ready SaaS application. The project involves maintaining the current dark theme UI and core client-side logic while building a robust backend to support user authentication, subscription billing, and data management.

System Overview

The system will be a SaaS application that allows users to generate SEO-friendly text variations using spintax. It will include user authentication, subscription management, and a scalable backend to handle user data and sessions. The application will be secure and ready for public launch.

Product Interpretation and Delivery Boundary

The application will maintain the existing dark theme UI and client-side logic. It will require user authentication and a monthly subscription via Stripe for access. The backend will manage user sessions and data securely. The application will be scalable to handle increased usage and suitable for public launch.
