A runaway trolley will kill 5 people. You can pull a lever to divert it, killing 1 person instead. Do you pull it?

How it works

Each dilemma is one real Jev decision. You choose first, then we ask Jev the same question — it returns a calibrated yes/no probability in a moment — and reveal whether you and the AI agree. At the end you get an agreement score across all the dilemmas.

Jev is a fast, cheap decision model, not a moral authority: it returns a probability, not a truth. The fun is seeing where your intuition lines up with the AI's — and where it doesn't.

FAQ

Does Jev really decide each dilemma?

Yes — each one is a real Jev API call returning a calibrated probability. It is not a scripted answer key; it's a live decision with a confidence.

Is it free?

Yes — it runs in your browser with no API key, each of Jev's calls is free and rate-limited. The whole set costs a fraction of a cent.

Should I take the AI's answers as moral truth?

No. Jev returns a fast, calibrated probability — a decision, not a verdict on right and wrong. Treat it as a fun comparison, not ethical guidance.
