Transaction tagging
Your transactions, categorized before you finish your coffee
Piggey reads merchant names, amounts, and patterns — then assigns categories automatically. Fix the odd one, teach it a rule, and accuracy compounds over time.
Try AI categorization freeInstant on import
The moment your CSV lands, every row gets a category — dining, groceries, subscriptions, transfers. No manual tagging marathon.
Rules for the rest
One correction becomes a rule: "Always categorize STARBUCKS as Coffee." Piggey applies it to past and future transactions.
Learns your habits
Unusual merchants get a best guess; you confirm once. Over time, categorization accuracy approaches perfect without babysitting.
Why categorization matters
You can't answer "where did my money go?" until transactions have meaningful labels. Spreadsheets die here — hundreds of rows, zero structure.
Piggey handles the grunt work. Import once and your spending breakdown is ready: dining vs groceries vs subscriptions, month over month, without a single formula.
