Make a real decision before you sign up for anything.
Name the options, say what matters, rate how each option performs — then let the same Monte Carlo engine that powers DCZion tell you which option wins and how fragile that answer is. No account, no email, no card.
One thing to know up front: this trial is the solo half of DCZion. The product is built for teams — and a team decision needs each member to sign in, so it starts with an account. That part is free.
Solo decisions only
This trial runs the one-person analysis. Team decisions are DCZion's real strength — they need every member to sign in, so they start with a free account (yours includes a 5-person team).
3 simulations a day
Run the full analysis — criteria, ratings, Monte Carlo, the winner — three times per day per browser. Incognito or another browser resets it; it is a soft limit, not a wall.
Nothing is saved
There is no account behind this page, so nothing you type is stored — not on our servers, not in your browser. Leaving or refreshing discards the work.
No downloads
PDF and JSON exports belong to an account. The trial shows the result; saving it, exporting it and inviting a team all need a free account.

This trial is the solo half of DCZion — team decision-making, where it is strongest, needs every member to sign in, so it starts with an account. Nothing you enter here is saved and exports are turned off; leaving the page discards your work.
A free account includes team decisions with up to 5 people, 10 a month — plus saving and exports. Paid plans are for bigger workspaces, not for unlocking your team.
Frame the decision
Pick the starting point that fits best — it pre-loads the evaluation criteria for you. Then name the decision and list the options you are choosing between.

One opinion is a guess. Your team’s is a decision.
Everything above came from you alone. DCZion exists for the case with more than one informed person in the room — the hiring panel, the budget committee, the leadership team — where the hard part is not the arithmetic but getting honest judgment out of people who report to each other.
Blind, independent scoring
Each member rates the options privately, in confidence ranges. Nobody sees anyone else’s numbers, so rank and the loudest voice cannot bend the result.
One verified answer
The same Monte Carlo engine runs on the team’s pooled ranges and returns the Condorcet winner, win probabilities, and a disagreement map showing exactly which criteria the team is split on.
A record you can defend
Every decision, who scored what, and when — auditable long after the meeting, so the reasoning survives the people who made it.
A free account is enough to start deciding with your team.
It includes team decisions with up to 5 people per workspace, saving, drafts and exports — 10 team decisions a month, no card. Bigger workspaces are where paid plans begin.
