facturillo keeps your Panamanian receipts ("facturas") organized automatically — scan the DGI QR code and every line item, vendor, and total is captured. This app connects ChatGPT to your facturillo account with read-only access, so you can ask natural questions about your real spending: "How much did I spend on groceries last month?", "Where did I buy this?", "Which store do I visit most?". Answers come from your actual receipt data — totals, line items, vendors, payment methods — never estimates. Requires a facturillo account (facturillo.com); data features require an active plan.
