Why BlazeDocs Achieves Higher Accuracy
🧠Advanced AI Model
BlazeDocs uses Mistral AI's latest vision-language model, specifically fine-tuned for document understanding. This allows us to understand context, not just extract pixels.
📐Layout Analysis
Our engine analyzes document layout before extraction, identifying tables, columns, and reading order—something basic text extractors miss completely.
🎯Semantic Understanding
We don't just convert—we understand. BlazeDocs recognizes when text is a heading, a list item, or a code block, ensuring proper Markdown syntax.
🔄Continuous Improvement
Our AI model is continuously updated with new training data from real conversions, improving accuracy over time without requiring software updates.
