Turn a decision into a model you can see.

A free tool for weighing choices with more than one thing to consider. Lay out your options and what matters, rate them — and Odesys draws how they compare.

The idea

A decision, drawn

Take an everyday one — what to have for dinner — and follow it through. This is what Odesys hands back.

“What to have for dinner?” Pizza vs Sushi, judged on three things.

PizzaSushi

Each line is one option. Left of the neutral line it’s worse on that factor; right of it, better.

Pizza comes out ahead — its clear win on taste outweighs sushi’s lead on time, with price near-even.

Odesys weighs it all and draws the chart — an ABACON — ranking your options.

Decide together experimental

A group that has to reach a conclusion

More people rating the same thing is a survey. A group decision is a process: build the frame together, judge alone, then count by a rule the group chose before it saw the result — and ask whether everyone can live with it.

1
Frame together
Everyone proposes options and factors from their phone; the facilitator merges duplicates and locks one frame.
2
Judge alone
Each person orders the factors and rates the options, anonymously, before seeing anyone else. The board shows only a count until the facilitator reveals.
3
Reach a conclusion
The board names the one factor or rating worth talking about first, lets people revise in a second round, counts by the chosen rule, shows what the other rules would have said, and records who can live with it.

Works on a projector and every phone in the room — nothing to install, nothing to sign up for.
