About Slipsee

A small app with a simple opinion: you should know where your money goes.

Not to the cent, not in a spreadsheet — just honestly, in a way that changes what you do next week.

Why receipts?

Most money apps start by asking for your bank login. That gets you a firehose of transactions — “$47.83, CARD PURCHASE, POS TERMINAL” — and none of the detail that actually explains your spending. The bank knows you went to the café. Only the receipt knows you bought two lattes and a cheesecake, and that the latte cost a dollar more than it did in spring.

Receipts are the richest record of everyday spending that exists, and they’re already yours: no institution in the middle, no permissions to grant. They just needed a better home than a coat pocket.

What Slipsee does with them

You scan a slip; your iPhone crops and straightens it before it ever leaves the device. Slipsee then reads the receipt — merchant, every line item, tax, total — and files it as structured data you can question.

Four kinds of signals come out of that one source of truth: category trends, habits, price changes on things you buy again, and gentle nudges when a month starts running hot. When you ask a question in plain English, answers are computed from your own receipt history and cite the slips they came from.

What Slipsee is not

It’s not a budgeting system, an expense-report tool, or a chore. There are no envelopes to fill and no categories to reconcile on Sunday night. Slipsee is for awareness: the moment you notice the latte went up, or that “groceries” quietly became “groceries and snacks.”

House rules

• Accuracy over vibes. Money math is exact, computed from your data, never estimated by a model.
• Privacy is not a tier. Encrypted at rest, per-receipt delete, no GPS, no bank logins.
• Awareness, not accounting. Nudges and trends that change next week, not ledgers that judge last month.
• Your data stays yours. Every receipt is editable forever and deletable in one tap, image and all.

Built with care

Slipsee is a native iOS app, designed to feel like paper and ink: warm, quiet, and legible. Under the hood it treats money the way a bank would — amounts stored exactly, insights computed deterministically, and AI used only where it genuinely helps.

It’s made by a small team that keeps its receipts. Questions, ideas, or a receipt that stumped the scanner? We’d love to hear about it.
