You make thousands of decisions — and remember the reasoning behind almost none.
So you don't learn. You drift. The enemy isn't any one bad call — it's deciding on autopilot.
You replay the same decision at 2am — and still can't tell if it's right.
Last month's pro/con list? Gone. So you keep relearning the same lessons.
You make choices to impress other people, not to match who you want to be.
You judge a decision by how it turned out — even the parts you couldn't control.
Generic AI just validates whatever you were already leaning toward.
Most apps journal your feelings. Decize journals your decisions — and scores each one against the values you chose.
In a 60-second setup you pick 3–6 core values that define you. From then on, they're the spine of everything: every option the AI maps, every lesson it pulls, every pattern it shows you is weighed against your values — not generic advice.
Pick from 12 · change them any time
What matters most to you?
Pick 3–6. We weigh your decisions against them.
Clarity in one sitting — depth over time
Capture the decision
Type or speak it in a sentence. Optionally tag your gut feel and confidence — the signals that later prove whether your judgment can be trusted.
Decide — or log the lesson
Decide now and the AI maps your options into paths scored against your values, with a 'Strongest value match'. Or just log it and it pulls out the lesson.
Come back when it plays out
Record how it actually turned out — no rushing a verdict. Over time, Decize tells you where your confidence and gut are reliable, and where they aren't.
Change what you value — watch the recommendation change
This is the heart of Decize: the same decision, scored against your values. Tap the values that matter to you.

The AI decision journal
Find out whether your judgment can be trusted.
Decize quietly records your confidence and gut feeling at decision time. As your decisions play out and you record how they landed, it joins the two — and tells you where you're calibrated and where you're fooling yourself.
Unlocks once a handful of your decisions have played out — it gets sharper the longer you use it. No competitor can hand you this on day one; it's built from your own track record.
Your most confident calls go well 0% of the time — less than your cautious ones. Watch for overconfidence.
When your gut said yes, it worked out
You under-estimate impact on big calls
Illustrative — your numbers are built from your own decisions
Built on a simple, research-backed idea
Record your reasoning beforeyou know how it turns out, and judge a decision by its process — not its result. Decision scientists call the opposite trap “resulting.” Decize is designed to engineer it out.

“Scoring a job offer against my actual values — instead of what would impress people — was the first time a decision felt clear instead of loud.”
“Seeing how my past 'sure things' actually turned out humbled me. I trust my gut differently now, in a good way.”
“It's the only journal I've kept for more than a week, because it actually closes the loop instead of just collecting entries.”
