A decision-support tool that aggregates verified data on taxes, cost of living, healthcare, internet, safety, visa/residency requirements, and tax-residency triggers for every country and major city. Users input their nationality, income, family situation, and priorities to receive personalized side-by-side rankings, plus alerts on residency-day thresholds and tax implications of cross-border moves.

Remote work has made cross-border living mainstream, but tax authorities (CRA, ATO, HMRC, IRS) are increasingly scrutinizing residency status while housing affordability crises push people to consider buying or living abroad.
