As of 13 August 2026, AI can compare different ways to repay your credit cards.

This still needs a person who signs their name to it.

What the alternative costsA purpose-built alternative is Julius AI, which analyses uploaded spreadsheets and produces charts and analysis.

If this goes wrong: you rely on an incorrect rate or an unrealistic repayment amount and pay more interest, incur charges or miss payments.

A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

How to actually do it

Open each current credit-card statement and lender terms, then gather the balance, interest rate, minimum payment, due date, fees and any promotional expiry date for every card.
Write down the total amount you can reliably pay towards all cards each month after essential household costs, without counting uncertain income or borrowing.
Record any savings buffer, new spending, missed payments, arrears, priority debts or court action that could change the repayment order.
Paste the gathered figures into the prompt, keeping one clearly labelled section for each card and stating when a figure is unknown.
Ask the chatbot to compare minimum payments, avalanche, snowball and any balance-transfer option only when you have supplied the offer terms.
Compare its balances, rates, fees, dates and estimated totals against the statements and lender terms, correcting every mismatch and asking it to recalculate.
Use the checked comparison to choose a payment order, set at least the required minimum for each card, and contact a free UK debt adviser if the plan does not cover essentials and minimum payments.

Prompt

Compare repayment strategies for my UK credit cards using only the figures I provide. Do not invent rates, fees, dates, balances, income or legal rules, and do not assume that a balance transfer or new credit will be available. Compare paying only the minimums, the debt avalanche method, the debt snowball method and any balance transfer option only if I provide its rate, fee, credit limit and promotional expiry date. Use these details: [card name, balance, purchase APR, cash APR if relevant, minimum payment formula or amount, payment due date, annual fee, promotional rate and expiry date for each card]; [amount I can pay towards all cards each month]; [regular income and essential monthly spending]; [cash savings or emergency buffer]; [any missed payments, arrears, court action or priority debts]. Show your assumptions, calculate the estimated interest and repayment order for each strategy, and explain which figures I must confirm with each lender. Separate arithmetic from judgement. Flag anything that could change the result, including promotional expiry dates, fees, variable rates, new spending and affordability. Do not tell me to miss a minimum payment or prioritise credit cards over priority debts. End with a short checklist of figures I should verify against my statements and lender terms. This is not professional advice. If I mention arrears, priority debts, court action or that I cannot afford essentials and minimum payments, say that I should speak to a free UK debt adviser rather than relying on the comparison.

Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

What it gets wrong

AI cannot know whether the repayment amount is genuinely affordable when your income or spending is unstable.
AI cannot see unprovided lender changes, fees, credit limits or promotional terms.
AI cannot decide how to weigh a mathematically cheaper plan against stress, cash-flow risk or the need for an emergency buffer.
AI cannot take responsibility if you miss a payment or follow an incorrect comparison.
AI cannot replace a debt adviser when you have priority debts, arrears, court action or no affordable payment plan.

Even on a YES, the friction has a name: judgement under ambiguity, verification cost and stakes of error.

FAQ

Can AI tell me which credit card to pay off first?: Yes, it can compare the debt avalanche order, which usually targets the highest interest rate first, with the debt snowball order, which targets the smallest balance first. Check every rate, fee and promotional expiry date against your statements before acting.
Is it better to pay off the smallest credit card first?: The smallest-balance method can give you an early cleared account, while paying the highest-rate card first may reduce interest. The right comparison depends on your actual balances, rates, fees and affordable monthly payment, so do not rely on a general rule.
Can AI work out how long it will take to pay off my credit cards?: It can estimate the timetable if you provide accurate balances, rates, minimum payments and a fixed monthly payment amount. The estimate changes if rates, fees, minimum-payment rules or spending change, so recalculate it against current lender information.
Should I use a balance transfer to pay off my credit cards?: AI can compare a balance-transfer offer if you provide its fee, rate, credit limit and promotional expiry date, but it cannot know whether you will be accepted or whether the payment remains affordable. This is not professional advice, and serious arrears or unaffordable debt need a free UK debt adviser.
