Overview

End-to-end automation of receipt capture and logging

The AI agent scans Gmail for unread messages labeled 'receipt', downloads attachments, and uses AI to extract key fields. It stores the original PDFs in a Google Drive folder and logs the parsed data (date, merchant, category, description, subtotal, tax, total) as a new row in a Google Sheet. The agent runs on a schedule, marks processed emails as read to prevent duplicates, and supports year-end audits with a single source of truth.
