Like a spreadsheet — but more powerful, with AI built in.
If you can fill in a spreadsheet, you already know how to use PiggySize: you type in the numbers you already know — rent, paycheck, balances — not every coffee and grocery run. Then it does what your spreadsheet can’t — debt payoff dates, a retirement plan projected year by year, what-if scenarios, and an assistant you can ask about your own money in plain English.
- No formulas to write, no VLOOKUP to fix
- The retirement and payoff math your sheet can’t do
- Still no bank connections — your numbers, your typing

“Why can’t I just ask ChatGPT?”
Fair question. Three reasons:
A chatbot forgets your numbers.
Every chat starts from scratch — you’d re-type your whole financial life each time, and hope it remembered right. PiggySize keeps your numbers in one place, so every answer starts from your real figures instead of whatever you managed to paste in.
Retirement has too many moving parts.
Social Security timing, pensions, withdrawals, taxes — dozens of rules that all affect each other over decades. That’s not a chat answer; it’s a planning engine, worked out year by year to age 95.
Chatbots guess at math. Piggy uses a calculator.
AI is confident — and sometimes confidently wrong — at arithmetic. Piggy is built to hand the math to a real calculator instead of doing it in its head, so the arithmetic is computed, not guessed.
Piggy answers from your actual numbers — and if you’d rather skip AI, you can switch it off completely.
