Installation

Prerequisites

• Python 3.8 or higher
• Google Gemini API Key

Setup Steps

1. Clone or download the project

   cd "New folder"
   

2. Create a virtual environment (recommended)

   python -m venv venv
   .\venv\Scripts\Activate.ps1

3. Install dependencies

   pip install -r requirements.txt

4. Get your Gemini API Key

   • Visit: https://makersuite.google.com/app/apikey
   • Create a new API key
   • Copy the key

5. Set the API Key environment variable

   PowerShell:

   $env:GEMINI_API_KEY='your-api-key-here'

   Command Prompt:

   set GEMINI_API_KEY=your-api-key-here

   Or create a .env file (optional):

   GEMINI_API_KEY=your-api-key-here
   

   Then load it before running:

   Get-Content .env | ForEach-Object {
       $key, $value = $_ -split '=', 2
       [Environment]::SetEnvironmentVariable($key, $value)
   }

Running the Application

1. Activate virtual environment (if using one)

   .\venv\Scripts\Activate.ps1

2. Set the API key (if not already set)

   $env:GEMINI_API_KEY='your-api-key-here'

3. Run the application

   python app.py

4. Open in browser

   • Navigate to: http://localhost:5000

How to Use

1. Open the application in your web browser
2. Click on the upload area or drag & drop a document
3. Select a file (PDF, Image, Word, PowerPoint, or Text file)
4. Click "Analyze Document" button
5. Wait for the AI to analyze your document
6. View the results and click "📋 Copy All" to copy the analysis to clipboard

File Format Details

Images (JPG, PNG, GIF, BMP, WebP)

• Analyzes image content, text within images, and visual elements
• Best for screenshots, diagrams, and photo documents

PDF

• Converts first page to image and analyzes content
• Extracts text and information from the document

Word Documents (DOCX)

• Extracts all text content
• Analyzes structure, paragraphs, and formatting

PowerPoint (PPTX)

• Extracts text from all slides
• Provides slide-by-slide analysis

Text Files (TXT)

• Reads plain text content
• Provides summary and key information

API Limits

• File Size: Maximum 50MB per upload
• Free Tier: Check Gemini API documentation for rate limits
• Processing Time: Depends on file size and complexity

Troubleshooting

Error: "GEMINI_API_KEY environment variable not set"

• Make sure you've set the API key environment variable correctly
• Restart the application after setting the variable

Error: "File type not allowed"

• Check that your file has the correct extension
• Supported formats: PDF, JPG, JPEG, PNG, GIF, BMP, WebP, DOC, DOCX, PPT, PPTX, TXT

Error: "Unable to process PDF"

• Install pdf2image: pip install pdf2image
• On Windows, you may need: pip install pdf2image pillow

Connection Error

• Make sure the Flask server is running
• Check that you're accessing http://localhost:5000
• Check firewall settings

API Rate Limit Error

• Wait a few minutes before making another request
• Check your Gemini API quota at https://makersuite.google.com
