System Requirements Document (SRD)

Project Name: pearl-app

1. Introduction

The pearl-app is a premium mobile application designed to automate YouTube content creation using AI. The app empowers users to create, manage, and grow their YouTube channels with minimal effort, offering a complete "AI-powered content business system." With a focus on simplicity for beginners and advanced tools for serious creators, the app aims to revolutionize content creation and channel growth.

This document outlines the system requirements for the pearl-app, focusing on delivering a Minimum Viable Product (MVP) in Phase 1, with scalability for future phases.

2. System Overview

The pearl-app is designed to automate the end-to-end process of YouTube content creation. It leverages AI to generate scripts, convert them into voiceovers, create videos with subtitles, and produce thumbnails. The app also integrates with YouTube for seamless uploads and provides analytics and growth suggestions in later phases.

The system will be built with a modular, API-driven architecture to ensure scalability and flexibility for future features like multi-platform publishing and advanced optimizations.

Key Features (MVP):

• AI script generation for shorts and long videos.
• AI voice synthesis in multiple languages (Hindi, English, Hinglish).
• Basic video creation with subtitles.
• Simple thumbnail generation.
• Clean and fast UI/UX for a seamless user experience.

3. Functional Requirements

Phase 1 (MVP):

• As a User, I should be able to log in or sign up.
• As a User, I should be able to select or get AI-suggested niches.
• As a User, I should be able to generate AI scripts for shorts and long videos.
• As a User, I should be able to convert scripts into AI-generated voiceovers.
• As a User, I should be able to create basic videos with subtitles.
• As a User, I should be able to generate simple thumbnails.
• As a User, I should be able to preview and download/export the generated content.

Phase 2:

• As a User, I should be able to auto-upload videos to YouTube.
• As a User, I should be able to view an analytics dashboard.
• As a User, I should receive AI-driven growth suggestions.

Phase 3:

• As a User, I should be able to enable "Auto Mode" for full channel automation.
• As a User, I should be able to publish content to multiple platforms (e.g., Instagram Reels).
• As a User, I should be able to perform A/B testing for thumbnails.
• As a User, I should be able to analyze competitors for niche discovery.

4. User Personas

1. Beginner Creator:

   • New to content creation.
   • Needs simple tools to get started.
   • Likely to use the free or Basic plan.

2. Intermediate Creator:

   • Has some experience with YouTube.
   • Wants to grow their channel with better tools.
   • Likely to use the Pro plan.

3. Professional Creator:

   • Relies on YouTube as a primary income source.
   • Needs advanced automation and analytics.
   • Likely to use the Auto Mode plan.

5. Visuals Colors and Theme

Unique Color Palette:

• Background: #121212 (Deep Black)
• Surface: #1E1E2E (Dark Slate)
• Text: #F5F5F5 (Soft White)
• Accent: #FF6F61 (Vibrant Coral)
• Muted: #6C757D (Muted Gray)

Theme:

The app will feature a dark premium UI with a neon gradient accent. Smooth animations and a modern, mobile-first design will enhance the user experience.

6. Signature Design Concept

The pearl-app will feature a "Neon Studio" landing page as its signature design concept.

Details:

• Visuals: The homepage will resemble a futuristic content studio with glowing neon elements. Each feature (script, voice, video, thumbnail) will be represented as a glowing, interactive icon.
• Animations: Icons will pulse and emit light trails when hovered over. A subtle parallax effect will create depth as users scroll.
• Interactions: Users can "drag and drop" icons into a central workspace to simulate the content creation process.
• Color Shifts: The neon gradient will subtly shift colors (e.g., coral to teal) as users interact with the page.
• Micro-interactions: Buttons and icons will have tactile feedback, such as slight vibrations or sound effects.

This immersive design will make the app feel like a cutting-edge tool for creators.

7. Non-Functional Requirements

• Performance: The app should load within 2 seconds on 4G networks.
• Scalability: The architecture must support up to 1 million users.
• Availability: 99.9% uptime.
• Security: User data must be encrypted (AES-256).
• Localization: Support for Hindi, English, and Hinglish.

8. Tech Stack

Frontend:

• React Native for mobile app development.

Backend:

• Python with FastAPI for scalable API development.

Database:

• MySQL for structured data (e.g., user accounts).
• MongoDB for unstructured data (e.g., media metadata).

AI Models:

• GPT 5.4 for script generation.
• Gemini 3.1 Pro for voice synthesis.
• Google Nano Banana for thumbnail generation.

AI Tools:

• LangChain for AI workflow orchestration.
• LiteLLM for LLM routing.

Orchestration:

• Docker for local development.
• Kubernetes for server-side orchestration.

9. Assumptions and Constraints

Assumptions:

• Users will have a stable internet connection.
• The app will initially target the Indian market (₹ pricing).
• Cloud storage costs will be manageable within the subscription revenue.

Constraints:

• Limited budget for initial development.
• Dependency on third-party APIs for AI and YouTube integration.
