Free tools
The precise ones.
Small, exact tools for the questions that decide where you can live: how long you can stay, who gets to tax you, and what you actually keep. Free to use. Every figure carries the sample-data note until the trust layer lands.

The whole picture
Or design the whole year at once.
The world builder lays your countries across a 365-day year and runs the Schengen clock, tax residence and citizenship together, live, as you move the days.
More tools are on the way: cost-of-living compare, golden-visa cost and ROI, a citizenship-timeline calculator and a relocation-cost estimator.
