Extract Data from Invoices and Receipts with AI
OCR invoices and receipts, then use AI to pull vendor, date, totals and line items into structured data.
OCR first
Photos of receipts go through Screenshot to Text; PDF invoices through PDF to Clean Text. A month of expenses can be processed together with the Batch Document Extractor.
Ask for fixed fields
Give the model a schema: vendor, date, invoice number, subtotal, tax, total, currency, line items. Fixed fields make results consistent across hundreds of documents.
Verify the money
Ask the model to flag when line items do not sum to the subtotal. Spot-check a sample against originals before importing into accounting software.

Frequently asked
Can AI add up line items?

What format should I request?
JSON or a CSV-style table with fixed field names, so results paste into spreadsheets.
