Decision Maker: Let AI Decide Between Two Options

Stuck between two options? Write them down with a bit of context and Jev picks one, with a confidence score and a one-line reason.

How it works

  1. 01Write the two options you're stuck between and, if you can, a few lines about your situation: what matters, what's at stake.
  2. 02Both options and your context are sent to Jev, TypeSafe's System One model, which picks one and returns a probability for each. It's asked twice with the options in opposite orders, and the answers are averaged.
  3. 03A second model, Gemini, writes a one-line reason for the pick. If it's unavailable you still get the verdict.
  4. 04The verdict is stamped with Jev's confidence, and the model, tokens and cost of the run are printed underneath.

Questions

How does the AI decision maker choose?

Jev reads both options and your context, then returns a probability for each one being the better choice for you. The option with more probability wins, and the gap between them is the confidence. The one-line reason is written afterwards by a separate model.

Is it better than flipping a coin?

A coin ignores your situation; this doesn't. When the result says "close call" it's close to a coin flip, and that's useful too: it means either option is defensible. Many people find their gut reaction to the verdict is the real answer.

What should I write in the context box?

Write what you'd tell a friend: your goal, your constraints, what you're afraid of. "I have 8 months of savings and I've stopped learning" changes a job decision far more than the options alone. Without context, Jev picks for a typical person.

Why do I get the same answer every time?

Same options and same context give the same verdict, and repeats are cached so they're instant and free. To test how sensitive the decision is, change a detail in your context or swap A and B. The order doesn't matter, because Jev is asked both ways.

Can it decide between more than two options?

This tool is built for two. For several options, compare them in pairs, or put them in the Tier List Maker with your criterion as "rank by".

Should I trust an AI with a big life decision?

Use it as a tiebreaker and a second opinion, not as the decision. It's good at weighing what you've written down; it doesn't know what you left out. If the verdict surprises you, ask yourself what context you didn't give it.
