DailyVox builds a private model of you — entirely on your iPhone, nothing collected, nothing transmitted. That architecture has a consequence we refuse to dodge: nobody can check the model works by watching a server, because there isn't one. So we measure it the hard way, in the open, and we publish what we find — including the failures. The next measurement needs a handful of real people. Maybe you.
One honest question, precisely stated: how well do the Twin's estimates of your traits agree with how you see yourself? You journal by voice; the model estimates seven things about your style of expression; you answer seven short questions about yourself; we compute the agreement — and compare it against a baseline that guesses blindly. If the model can't beat the blind guess, we say so in public. We've already published one negative result on the developer's own twenty-year diary; the instrument is real.
Full documents: participant sheet · consent note · the public research kit. This is an independent, unpaid, consented study run by the developer as an independent researcher; it is not a university study.
The first wave is deliberately small — a handful of people, measured carefully, reported honestly. If you journal in English on an iPhone and are 18 or older, you're eligible.
