Features
Everything you need to run shared ownership — clearly, fairly, and without spreadsheets
Kai is an operating system for shared assets. It replaces ad-hoc calendars, manual cost splits, and awkward conversations with a single, transparent system.
Everything is organized around a group — for example aircraft owners, car co-owners, or shared equipment teams.
