Data River uses a proprietary AI model trained specifically on financial document layouts. Unlike generic PDF converters, our system understands the unique structure of bank statements from thousands of financial institutions.

The Technical Approach

1. Document Analysis: Our AI analyzes the visual layout of your statement, identifying tables, columns, and transaction data based on learned patterns from thousands of bank formats.
2. Bank-Specific Parsing: We maintain parsers optimized for each major bank's statement format, including their quirks like multi-line descriptions, wrapped text, and varying column structures.
3. Validation: Every conversion validates that opening balance + transactions = closing balance, catching extraction errors before you download.
4. Format Conversion: Extracted data is structured into clean CSV files with consistent column headers, ready for Excel, Google Sheets, or accounting software.

What We Don't Do

• We never send your files to third-party AI APIs (OpenAI, Claude, etc.)
• We don't store your bank statements after processing
• We don't use your financial data to train our models
• We don't require access to your bank account credentials

Accuracy & Limitations

Our system achieves high accuracy on most digital PDF statements from major banks. However, accuracy can vary based on:

• Statement quality (digital PDFs work better than scanned images)
• Bank format complexity (some international banks use non-standard layouts)
• Document condition (poor scans, low resolution, or heavy redaction can impact results)

We recommend always verifying your converted data against the original statement, especially for financial reconciliation or tax purposes.
