One confident number vs a panel that argues.
Preuve is a genuinely thorough evidence engine — it pulls live data and cites its sources, and that's real. But it collapses everything into a single score, gates the reasoning behind a signup, and keeps its track record for paying subscribers. Skeptral shows the models disagree, names the one argument most likely to kill your idea, and gives you the whole verdict free — no signup. Its pool of past verdicts is public and auditable.
The feature matrix
Evidence report vs adversarial verdict.
If you want a 15-section investor-grade dossier with sourced market data and you're ready to pay for it, Preuve is a serious tool. If you want an honest, decisive gut-check before you build — one that shows you where independent models disagree and states the single strongest case against you, free and in a minute — that's exactly what Skeptral is for. Many founders will use Skeptral first to decide whether the idea is worth a paid deep-dive at all.
