Real questions, two answers each — and the decision Decider made
These are recorded Decider runs, reviewed one by one before publication. Same shape every time: a question, two candidate answers, a pick, a calibrated confidence value and the reasoning that came with it. They are here so you can judge the product on real work rather than on a demo script.
Reading the confidence value: 90%+ means decisive, 80–90% a clear edge, 70–80% act after a quick look, below 70% a near-tie where either choice is defensible. It is a reading of how close the call was — not a promise that a pick is right. How it is measured →
