live-jev
2D autonomous car simulation in the browser, driven by TypeSafe's Jev decision model
questions: { throttle: choice, yaw: choice, pitch: choice, // +3 }
jev-autopilot
This demo uses Jev from TypeSafe AI to autonomously fly a drone in a random city from point A to point B, avoiding obstacles along the way. A trip costs $0.01.

chakravyuha-jev
Chakravyuha — a polar ring-maze where every move is a Jev (TypeSafe System One) decision. A fun experiment: the model picks each move, the walk grades it green or red, and the history page asks whether its confidence score can be trusted. BYOK, no build step.
questions: { intent: choice, connection: choice, supported: boolean, }
last-train-jev
A small detective escape room built with TypeSafe Jev, React, and Express.
