Pingpong is for independent consultants and advisors who pressure-test a recommendation before the client sees it. Paste the deck outline, memo, or strategy note. Five flagship AIs run in sequence: Grok, then Perplexity, then ChatGPT, then Gemini, then Claude. The first answers. Each later model gets your question, the prior answers, and a review frame that allows agree, correct, restructure, or reject a weak premise. You inspect the final answer and the earlier passes.
This is not legal advice. It is not a substitute for your judgment, your diligence, or the engagement you sold. It is a sequential review pass when a soft spot in the recommendation would land in front of a paying client.
Why single-model drafting is a bad last step
ChatGPT (or Claude alone) is fine for first drafts. It is weak as the last check before you send. One model fills gaps, flatters the framing you already like, and sounds sure. Asking the same chat again keeps the same blind spots.
Strategy, ops, and fundraising advice carry reputation risk. A clean narrative that hides a load-bearing assumption is how you get embarrassed in the room. Sycophancy research is why "sounds polished" is not the same as "safe to send."
Good questions to run
- Where does this recommendation leave a hole a skeptical client will attack first?
- Which premises in this memo are load-bearing and unstated?
- What breaks in this operating plan if the growth assumption is wrong by half?
- What did this fundraising narrative leave undefended for a careful investor?
- Given these options, which tradeoff is the client actually buying, and what would falsify it?
Attach the deck PDF, Word memo, spreadsheet, or screenshots when you can. Use Pro when the question is hard and you want extended thinking.
How the sequence helps a consultant
Default order: Grok, Perplexity, ChatGPT, Gemini, Claude. Order is configurable. Later models are allowed to reject a weak premise, not only polish wording. That is the product bet versus drafting in one chat. Details: how Pingpong works, how to run a Pingpong, and Pingpong vs ChatGPT.
You still decide. Pingpong is review before you send, not a guarantee and not a stand-in for your professional judgment.
