PivotProof vs ChatGPT: which one actually tells you your idea is bad?
General AI is useful for exploration. A hostile panel is designed to challenge the answer.
Use ChatGPT when
You need to brainstorm, rewrite, learn a concept, or work through options with a collaborative assistant.
Use PivotProof when
You want five hostile lenses, a quantified score, kill criteria, and an explicit challenge to the assumptions in your pitch.
The verdict
Use a general assistant to expand possibilities. Use a hostile panel to pressure-test the one you are considering building.
