Polite-It Technical Specification

1. Platform Architecture

Polite-It is built as a Chrome browser extension with backend support for API calls to a GPT-4-powered server. It integrates seamlessly into text boxes on supported platforms and provides a user-friendly interface for real-time text transformation.

2. Key Components

1. Frontend:
   • Framework: Built using JavaScript, HTML5, and CSS3 for lightweight and responsive design.
   • Pop-Up UI: Designed using React.js to ensure a dynamic and fast user experience.
   • Text Box Integration:
     • Uses the Chrome Extensions API to inject JavaScript into web pages.
     • Dynamically adds a Polite-It button to text fields on supported websites (e.g., WhatsApp Web, Facebook, Gmail).
2. Backend:
   • Server Framework: Node.js with Express.js for handling API requests.
   • Cloud Hosting: AWS or Google Cloud for scalability and reliability.
   • Language Processing: OpenAI GPT-4 API for text rewriting and tone adjustments.
   • Database:
     • Type: MongoDB or Firebase for real-time data storage and retrieval.
     • Data Stored:
       • User profiles (name, email, subscription type).
       • Usage data (message counts, tone preferences).
       • Payment history (Stripe/PayPal integration).

3. Key Features

1. One-Click Text Polishing:
   • Integrated directly into text boxes, users can click the "Polite-It" button for immediate text transformation.
2. Politeness Styles:
   • Three pre-defined styles: Co-Worker, Client, and Formal.
   • Style metadata is sent as part of API requests to adjust the rewritten tone dynamically.
3. Pop-Up Text Box:
   • A pop-up interface appears when clicking the extension icon in the browser toolbar.
   • Users can type or paste text, select a tone, and process their message.
4. Politeness Level Meter (Future Feature):
   • Real-time NLP-based analysis of text to detect tone and suggest politeness improvements.
5. Subscription Plans:
   • Free Plan: 5 total messages.
   • Standard Plan: 200 messages/month.
   • Pro Plan: 1,000 messages/month.
   • API rate limiting ensures message limits are enforced per user account.
6. Multilingual Support:
   • Powered by GPT-4's built-in capabilities to handle text in multiple languages without additional configuration.

4. Technical Requirements

1. Browser Compatibility:
   • Supported on Google Chrome (latest version).
   • Future support planned for Edge and Firefox browsers.
2. System Requirements:
   • Minimum: Windows 7, macOS 10.12, or equivalent Linux distributions.
   • Optimal: Windows 10+ or macOS 11+ with Google Chrome.
3. Extension Permissions:
   • Read and write access to specific text fields on supported websites.
   • Network access to send API requests.
4. API Integration:
   • OpenAI GPT-4 API for processing text.
   • Stripe and PayPal APIs for subscription management.
   • Google Firebase or MongoDB for database interactions.

5. User Authentication and Data Security

1. Authentication:
   • JWT-based authentication for secure and scalable session management.
   • OAuth integration for Google and Facebook login options.
2. Data Security:
   • All user data is encrypted in transit (HTTPS) and at rest (AES-256).
   • No sensitive data (e.g., message content) is stored permanently on servers.
3. Privacy:
