AI-Powered Processing
Learn how to use Gemini and Ollama AI models for invoice extraction
Introduction to AI Processing
Invoices Reader offers advanced AI-powered processing capabilities that go beyond traditional OCR and QR code reading. These AI models can:
- Extract data from complex invoice layouts
- Handle invoices without QR codes
- Process non-standard invoice formats
- Understand context and relationships between invoice elements
AI processing is particularly useful for invoices that don't follow standard formats or don't include QR codes. The AI can "understand" the document context and extract relevant information even from varied layouts.

Best Practices for AI Processing
Image Quality Matters
AI models perform better with clear, high-resolution images. Ensure your invoices are scanned at 300 DPI or higher, and the text is clearly visible.
Test Different Models
Try processing the same invoice with different AI models to see which gives the best results for your specific invoice types.
Verify Results
Always verify the extracted data against the original invoice, especially for critical fields like amounts and tax information.
Batch Similar Invoices
Process similar invoices (same vendor or format) together using the same AI model for more consistent results.
