AI compares your current city against your target on cost of living, housing, jobs and lifestyle — plus a calculator that works out what the move does to your purchasing power using your own numbers.
$80K in one place and $80K in another are not the same income, and the gap is mostly housing. Most people compare the salary and skip the rest.
State and local taxes, car insurance, utilities in a different climate, childcare, and the price of flying back to see everyone. None of them appear in the rent listing you've been staring at.
They don't know your income, your family size, what you actually spend on, or whether your job survives the move. An average household isn't a household.
You fall for a city on holiday, decide, and assemble the evidence afterwards. Ranking your priorities before you see any scores is the small discipline that prevents it.
