What you can do

• Share one family budget with your partner, each on your own phone
• Keep shared categories (groceries, rent, kids) next to personal ones only you see
• Use monthly, yearly and rolling envelopes — yearly bills are spread across 12 months
• Fund savings goals in a set order and split a surplus between them
• Track debts with interest, overpayments and a projected payoff date
• Record income and see your monthly surplus and savings rate
• Log an expense by typing “45 on groceries” to the free AI assistant
• Ask Claude or ChatGPT about your budget through the official MCP server

How it is different

• Built for two: privacy between partners inside one shared budget, not just a shared login.
• No bank login: nothing to link, re-authorise or repair; your bank credentials stay with your bank.
• Envelopes for real life: yearly and rolling categories handle insurance, holidays and big goals.
• AI that asks first: the assistant prepares entries and saves nothing until you confirm.

Who makes it

FamilyJar is built by Rafał Gawlik, a husband and father in Kraków, Poland. He writes about family budgeting, the envelope method and building financial security as a couple, drawing on the workflows behind the app and on running his own household budget.
