                    <h2>The AI Revolution in Data Extraction</h2>
                    <p>Artificial Intelligence has fundamentally transformed data extraction from a manual, time-intensive process to an automated, intelligent capability that can handle complex, unstructured data sources with remarkable accuracy. In 2025, AI-powered extraction systems are not just faster than traditional methods—they're smarter, more adaptable, and capable of understanding context in ways that rule-based systems never could.</p>
                    
                    <p>The impact of AI on data extraction is quantifiable:</p>
                    <ul>
                        <li><strong>Processing Speed:</strong> 95% reduction in data extraction time compared to manual processes</li>
                        <li><strong>Accuracy Improvement:</strong> AI systems achieving 99.2% accuracy in structured document processing</li>
                        <li><strong>Cost Reduction:</strong> 78% decrease in operational costs for large-scale extraction projects</li>
                        <li><strong>Scalability:</strong> Ability to process millions of documents simultaneously</li>
