PivotProof vs ValidatorAI: hostile panel or friendly checklist?
The choice is not about a longer feature list. It is about what kind of feedback changes a decision.
Use idea-validator tools when
You want a quick first-pass score, broad prompts, or a low-stakes exploration.
Use PivotProof when
You want the product to assume your idea has a flaw and make you prove it wrong.
The verdict
A checklist can show the questions. A hostile panel makes you answer them under pressure.
