System Requirements Document (SRD)

Project Name: mossy-web

1. Introduction

The mossy-web project, also known as CodeEase Assistant, is an AI-powered web application designed to assist users with coding and Excel-related tasks. The platform combines advanced AI capabilities with a clean, modern, and secure interface to deliver a professional and user-friendly experience. Targeted at both individuals and businesses, the application aims to streamline problem-solving, enhance productivity, and provide scalable solutions for real-world use cases.

This document outlines the system requirements for mossy-web, including functional and non-functional specifications, user personas, design concepts, and technical architecture.

2. System Overview

CodeEase Assistant is a SaaS (Software as a Service) product that leverages AI to provide solutions for coding and Excel-related queries. The application features a 3-part layout:

1. Left Sidebar: Displays saved formulas and chat history for quick access.
2. Center Chat Interface: Allows users to type questions and view AI-generated responses.
3. Right Solution Box: Displays generated code or Excel formulas with options to copy or save them.

Key features include:

• AI-powered responses for coding and Excel queries.
• User authentication with email/password.
• A free trial system (5 days) for new users.
• Subscription-based access with Razorpay integration for payments.
• Secure data handling and responsive design for a seamless user experience.

The system is designed to cater to both individual users and businesses, ensuring scalability and reliability.

4. User Personas

4.1 Individual Users

• Description: Freelancers, students, or professionals seeking quick solutions for coding or Excel-related tasks.
• Needs: Easy-to-use interface, reliable AI responses, and affordable pricing.

4.2 Business Users

• Description: Teams or organizations in tech, finance, or other industries requiring collaborative tools.
• Needs: Scalable access for multiple users, team management features, and secure data handling.

4.3 Admins

• Description: Internal team managing the platform's operations and user accounts.
• Needs: Tools for user management, subscription tracking, and system monitoring.

5. Visuals Colors and Theme

The CodeEase Assistant will feature a professional Navy Blue and White theme, ensuring a clean and modern aesthetic. Below is the unique color palette for the project:

• Background: #F5F9FF (Soft White)
• Surface: #E8EEF7 (Light Blue)
• Text: #1A1A2E (Deep Navy)
• Accent: #3B82F6 (Bright Blue)
• Muted Tones: #A1AFC3 (Muted Gray-Blue)

This palette ensures a professional and visually appealing interface that aligns with the application's purpose.

6. Signature Design Concept

The CodeEase Assistant homepage will feature a dynamic split-screen animation that visually represents the app's core functionality.

Concept Details:

• Left Sidebar Animation: A vertical timeline animation showcasing saved formulas and history as users scroll. Each item will "light up" with a glowing effect when hovered over.
• Center Chat Interface: A sleek, typewriter-style animation where user queries and AI responses appear as if being typed in real-time. Subtle pulsing dots will indicate the AI is "thinking."
• Right Solution Box: A card-flipping animation where generated solutions (code or formulas) appear as cards flipping into view. Users can hover over a card to see a "Copy" or "Save" button slide into place.
• Background Interaction: A subtle, flowing wave animation in the background, representing the seamless flow of AI-powered solutions.

This design will create an engaging and memorable first impression, emphasizing the app's modern and innovative nature.

7. Non-Functional Requirements

• The system must handle at least 10,000 concurrent users.
• Response time for AI queries should not exceed 2 seconds.
• All user data must be encrypted both in transit and at rest.
• The application must comply with GDPR and other relevant data protection regulations.
• The system should be 100% responsive and optimized for both desktop and mobile devices.
• The backend should support horizontal scaling to accommodate growing user demand.

8. Tech Stack

Frontend

• React for Web

Backend

• Python
• FastAPI

Database

• MySQL (with Alembic for migrations)

AI Models

• GPT 5.4 for user-friendly responses
• Claude 4.6 Opas for academic or coding work

AI Tools
