How it works

  1. You type a phrase. A word, a feeling, a place, a memory — anything up to 60 characters, in any language.
  2. Jev answers 67 questions at once. Jev is a “System One” model from TypeSafe AI. It doesn't write sentences; it returns calibrated probabilities. For each of 63 named colors it tells us how likely that color belongs to your phrase, and it rates the phrase on light, warmth, energy and mood.
  3. We paint the probabilities. The strongest colors get the most room; the motion follows the energy score; the text flips dark on bright fields. Every number on the page is Jev's raw answer. Nothing is hand-picked.
