Invoice Processor — AI-Powered PDF Data Extraction

An intelligent invoice processing tool that extracts structured data from PDF invoices using Claude AI (Anthropic) and presents the results in an interactive dashboard. Upload one or multiple invoices and instantly get a clean breakdown of vendors, amounts, dates, taxes, and line items — no manual data entry required.

What it does

The application reads raw PDF invoices and uses a large language model to understand their content regardless of format or layout. It identifies and extracts the key fields from each invoice, normalizes them into a consistent structure, and displays everything in an interactive Streamlit dashboard with charts and export options.

Extracted fields include:

• Vendor name and contact details
• Invoice number and date
• Line items with descriptions, quantities, and unit prices
• Subtotal, taxes (VAT/IVA), and total amount
• Payment terms and due date
