Paste it in — the month is already categorized

Three principles

01

Paste it, or snap it

Drop a card or bank CSV in — or photograph a receipt — and category, merchant, and recurring expenses get sorted automatically. Instead of an Excel macro.

02

A month on a single screen

No bloated charts. The whole month fits in one view — showing what shifted, not which day was expensive.

03

No bank account linking

Nothing is connected to your bank or card issuer — only CSV files and manual entry. Entries are stored under your own account in the Seoul region, and leave it only when you use an AI feature.
