Lovable Prompt Creator - AI Prompt Generator

## APPLICATION OVERVIEW
This application is a web app designed for autonomous PDF editing, allowing users to manipulate transaction lists within uploaded PDFs using AI and predefined configurations. Users can select specific transactions to modify, generate random values, and sync balances seamlessly, enhancing efficiency and accuracy in financial management.

## CORE FEATURES
1. **PDF Upload**: Users can upload a PDF file containing transaction data for editing.
2. **Transaction Selection**: A side panel allows users to select specific transactions to modify, either randomly or based on predefined rules.
3. **Random Value Generation**: The app can replace selected transactions with random numbers below a specified threshold, ensuring balance synchronization.
4. **Preconfigured Options**: Users can choose from multiple editing scenarios, such as removing high-value transactions and generating new ones based on user-defined parameters.
5. **Balance Sync**: Automatically calculates and updates the balance based on the changes made to the transaction list.
6. **Download Modified PDF**: After editing, users can download the updated PDF with the new transaction data.

## DESIGN SPECIFICATIONS
- **Visual Style**: minimalist - Clean, simple design with plenty of white space, minimal color palette, and focus on typography
- **Color Mode**: Light theme with dark text on light backgrounds
- **Primary Color**: #1978E5 (accent for buttons, links, highlights)

- **Border Radius**: 8px (moderately rounded) for buttons, cards, and inputs
- **Layout**: The layout will consist of a top navigation bar, a central upload area, a side panel for transaction selection, and a results area for displaying the modified transactions and balance.

## TECHNICAL REQUIREMENTS
- **Framework**: React with TypeScript
- **Styling**: Tailwind CSS
- **UI Components**: shadcn/ui
- **State Management**: Redux or Context API for managing application state

## IMPLEMENTATION STEPS
1. **Set Up Project**: Initialize a new React project with TypeScript and install necessary dependencies (React, Tailwind CSS, shadcn/ui).
2. **Create Layout Components**: Develop the main layout, including the navigation bar, upload area, side panel, and results section.
3. **Implement PDF Upload Functionality**: Use a library like `pdf-lib` to handle PDF uploads and parsing.
4. **Build Transaction Selection UI**: Create a UI for selecting transactions from the uploaded PDF and provide options for editing.
5. **Develop Random Generation Logic**: Implement the logic for generating random transaction values and syncing balances.
6. **Add Download Feature**: Allow users to download the modified PDF after edits are made.
7. **Test and Debug**: Ensure all functionalities work as intended, and fix any issues that arise during development.

## USER EXPERIENCE
Users will start by uploading a PDF file containing their transaction list. They will then see the transactions in the side panel and can select which ones to edit. After making their selections, they can choose to either generate random values or apply one of the predefined editing options. The application will automatically calculate the new balance, which will be displayed in the results area. Finally, users can download the updated PDF, completing the process in a streamlined and user-friendly manner.
