System Requirements Document (SRD)

Project Name: calm-image

1. Introduction

The calm-image project is an innovative platform designed to generate all types of realistic images, including unconventional or conceptual subjects such as a "nano banana." This system aims to provide a versatile and user-friendly experience for a wide audience, including designers, marketers, and creative enthusiasts. By leveraging cutting-edge AI models and a robust tech stack, calm-image will empower users to create visually stunning and highly customizable images based on their unique needs and imagination.

This document outlines the system requirements for calm-image, including functional and non-functional requirements, user personas, visual design elements, and technical specifications.

2. System Overview

The calm-image platform will serve as an AI-powered image generator capable of producing realistic and conceptual images based on user-provided text prompts. The system will support a wide variety of image types, from artistic creations to practical designs, ensuring versatility and creativity.

Key features include:

• Text-to-image generation using advanced AI models.
• Support for unconventional and conceptual subjects, such as "nano banana."
• Role-based access for free and premium users with varying feature sets.
• A visually appealing and intuitive user interface.

The platform will cater to users in India (IN) and globally, with locale-specific defaults such as Indian Rupees (₹) for pricing and IST (Indian Standard Time) for timestamps.

3. Functional Requirements

As User:

• I should be able to generate realistic images based on text prompts.
• I should be able to create unconventional or conceptual images, such as a "nano banana."
• I should be able to download generated images in multiple formats (e.g., PNG, JPEG).
• I should be able to customize image dimensions and resolution.
• I should be able to save my favorite generated images to a personal gallery.
• I should be able to share generated images directly to social media platforms.

As Premium User:

• I should be able to generate high-resolution images without watermarks.
• I should have access to advanced customization options, such as style filters and color palettes.
• I should be able to generate a higher number of images per day compared to free users.

As Admin:

• I should be able to monitor platform usage and user activity.
• I should be able to manage user roles (e.g., free vs. premium).
• I should be able to update AI models and system configurations.

4. User Personas

Free User:

• Description: Casual users exploring the platform for fun or occasional use.
• Goals: Generate a few images, experiment with prompts, and share creations on social media.
• Limitations: Limited daily image generation and watermark on images.

Premium User:

• Description: Professionals or enthusiasts requiring high-quality, customizable images.
• Goals: Access advanced features, generate high-resolution images, and use images for commercial purposes.
• Limitations: Subscription-based access.

Admin:

• Description: Platform managers responsible for maintaining system performance and user satisfaction.
• Goals: Monitor usage, manage user roles, and ensure the platform runs smoothly.

5. Visuals Colors and Theme

Unique Color Palette:

• Background: #F5F9FF (Soft Sky Blue)
• Surface: #FFFFFF (Pure White)
• Text: #2C3E50 (Deep Slate Gray)
• Accent: #FFB400 (Vibrant Amber)
• Muted: #D3DCE6 (Light Mist Gray)

This palette reflects a calm and creative atmosphere, aligning with the project's name and purpose.

6. Signature Design Concept

Interactive Canvas with Dynamic Prompt Visualization

The homepage of calm-image will feature an interactive canvas that visually responds to user input in real-time.

• Design Elements:

  • A floating 3D canvas in the center of the screen, surrounded by subtle animations of swirling particles.
  • As users type their text prompts, the canvas will dynamically display a conceptual preview of the image being generated, using abstract shapes and colors that evolve with each keystroke.
  • The background will feature a living watercolor effect that subtly shifts hues based on the mood of the prompt (e.g., warm tones for "sunset," cool tones for "ocean").

• Interactions:

  • Users can drag and rotate the 3D canvas to explore it from different angles.
  • Micro-interactions, such as button hover effects and smooth transitions, will enhance the user experience.

This bold and immersive design will make the platform instantly fascinating and encourage users to explore its capabilities.

7. Non-Functional Requirements

• The system should support at least 10,000 concurrent users.
• Image generation should not exceed 10 seconds per request.
• The platform should maintain 99.9% uptime.
• All user data must be encrypted and stored securely.
• The system should comply with GDPR and Indian data protection regulations.

8. Tech Stack

Frontend:

• React for Web

Backend:

• Python
• FastAPI

Database:

• MySQL (with Alembic for migrations)

AI Models:

• Google Nano Banana for image generation
• GPT 5.4 for user-friendly responses

AI Tools:

• Litellm for LLM Routing
• Langchain

Orchestration:

• Docker
• Kubernetes

9. Assumptions and Constraints

• The platform assumes users will have a stable internet connection for optimal performance.
• Image generation may be limited for free users to manage server load.
• The system will initially support English text prompts, with plans to add multilingual support in the future.

10. Glossary

• AI Models: Algorithms trained to perform specific tasks, such as image generation.
• Text Prompt: A user-provided description that guides the image generation process.
• Concurrent Users: The number of users accessing the platform simultaneously.
• Watermark: A semi-transparent logo or text overlay on images to indicate ownership or usage restrictions.
• Micro-Interactions: Small, subtle animations or effects that enhance user experience.
