About these finance tools
Money paperwork that runs entirely in your browser. The Receipt Scanner reads the merchant, date, and total from a photographed or dropped receipt with on-device OCR and files it into an expense ledger you can export as CSV. It keeps your receipts and spending on your machine instead of a vendor server, and it works offline once loaded, inside locked-down corporate networks, and on your phone.
Frequently Asked Questions
Do my receipts or financial data leave my device?
No. Every finance tool runs entirely in your browser. Receipt photos and the amounts read from them stay on your device; nothing is sent to a server.
How does the receipt scanner read a receipt?
On-device OCR reads the printed text, then the tool picks out the merchant, the date, and the total. You confirm or correct each field before it joins the ledger, and you can export the ledger as CSV.
