System Requirements Document (SRD) for project-aee2edc0

1. Introduction

The purpose of this document is to outline the system requirements for project-aee2edc0, a professional web application designed to serve as a PDF reader integrated with an AI-powered personal assistant. This application will allow users to upload and view PDF files, interact with an AI assistant for various tasks, and ensure seamless handling of large files up to 100 MB. The project is tailored to meet the needs of users in Egypt (EG), with a focus on multilingual support, simplified explanations, and advanced text-and-image interaction capabilities.

2. System Overview

project-aee2edc0 is a web-based application that combines PDF reading functionality with an AI-powered personal assistant. The system will enable users to:

• Upload and view PDF files, including large files up to 100 MB.
• Interact with a floating AI assistant for real-time assistance.
• Ask questions about the currently displayed page, with the assistant having access only to the content of that page.
• Translate the page into multiple languages.
• Simplify complex text explanations.
• Interact with both text and images, including scanned pages.

The system will prioritize user privacy and security by limiting the AI assistant's access to the currently displayed page only. It will also ensure smooth performance for large files and provide a user-friendly interface.

3. Functional Requirements

• As a User, I should be able to interact with a floating AI assistant by clicking on a floating ball icon.
• As a User, I should be able to ask the AI assistant to translate the currently displayed page into multiple languages.
• As a User, I should be able to ask the AI assistant to simplify complex text on the currently displayed page.
• As a User, I should be able to ask the AI assistant questions about both text and images on the currently displayed page, including scanned content.
• As a User, I should be able to receive accurate and context-aware responses from the AI assistant.

4. User Personas

1. General User:

6. Signature Design Concept

Floating AI Assistant with Dynamic Interaction

The homepage of project-aee2edc0 will feature a floating AI assistant ball that is both functional and visually captivating. The ball will have a subtle glowing animation to indicate its readiness for interaction. When clicked, the ball will expand into a sleek, semi-transparent chat interface that slides up from the bottom of the screen.

Key Features:

• Dynamic Glow Animation: The floating ball will emit a soft, pulsating glow in the accent color (#FF6F61), drawing attention without being intrusive.
• Interactive Expansion: Upon clicking, the ball will smoothly expand into a chat window with rounded corners and a gradient background blending the accent and muted tones.
• Micro-Interactions: The chat interface will include subtle animations, such as typing indicators, message bubbles that "pop" into view, and a progress bar for AI processing.
• Page-Specific Context: The assistant will display a small header indicating the current page being analyzed, reinforcing its page-specific functionality.
• Visual Feedback: When the assistant processes images or scanned content, a small "scanning" animation (e.g., a magnifying glass icon moving across the page) will appear.

This design concept ensures that the AI assistant is not only functional but also provides a delightful and memorable user experience.

7. Non-Functional Requirements

• The system must support PDF files up to 100 MB without performance degradation.
• The AI assistant must respond to user queries within 2 seconds on average.
• The application must support multilingual translation for at least 10 major languages.
• The system must ensure data privacy by restricting AI access to the currently displayed page only.
• The interface must be responsive and optimized for both desktop and mobile devices.
