Why tools matter
Quadratic voting becomes intuitive once people see that doubling intensity quadruples cost, and interactive tools make that tradeoff visible before participants enter a live decision.
Nicolas tools are educational and product-aligned. They use voice credits, signed vote intensity, and quadratic costs rather than pretending the mechanism is a simple poll.
What to calculate
The most important calculation is the spend of a vote vector, which is the sum of squared intensities across alternatives.
A calculator can show whether a participant is inside budget, how much budget remains, and why splitting intensity across independent voters is cheaper than concentrating it in one bundle.
