Scoring Philosophy
Most tools optimise for confidence; we optimise for honesty. The lower number is the trustworthy one.
~78
average score
Inflated, encouragement-led numbers. Almost every idea passes - which means the score is meaningless.
~50
median score
Cross-checked against live data and competitor reality. Only 18.3% of ideas earn a Go verdict - which is what makes it earn it.
A 54 from Preuve AI is more useful than an 82 from anywhere else - because it tells you what's actually weak.
