A living, structured model of your world — private and under your control.
A living model of your world built from your data and enriched by AI — more than storage, it is understanding, and it stays private and yours.
Industry uses digital twins for jet engines and factories: a live model of the real thing, fed by its data, accurate enough to ask questions of — what happens if this changes? — without touching the original. The idea transfers to a person more cleanly than it should be comfortable to admit.
The word doing the work is living. An archive is a record of what happened; a twin is a model that stays current and can be interrogated. The difference isn't volume — it's whether the thing can answer.
Which makes ownership non-negotiable rather than idealistic. A model of your world is the most valuable dataset about you that will ever exist. It belongs in your files, under your control — not in a service that models you for its own purposes.
