Pingpong is a second pass on your draft. Paste a memo, letter, clause set, or argument outline. Five flagship AIs run in sequence (Grok, Perplexity, ChatGPT, Gemini, 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 counsel, research, or firm process. It is hole finding before you send, file, or put a recommendation in front of a client or partner.
Where a single model is a bad idea
One chat can miss a counterargument, flatten jurisdiction, or agree with a premise you should not have accepted. Asking the same model twice keeps the same blind spots. Sequential review across providers is useful when the cost of a soft spot in the draft is real.
Good questions to run
- Where does this draft leave a hole a skeptical reader will attack first?
- Which assumptions in this memo are load-bearing and unstated?
- What competing reading of this clause fits the same facts?
- What did this settlement outline leave undefended for our side?
- Where does this issue list overclaim relative to the attached sources?
Attach the PDF, Word doc, or screenshots when you can. Use Pro when the question is hard and you want extended thinking.
Decision insurance, not a guarantee
"Decision insurance" here means review before commitment. It is not a financial insurance product. It is not a malpractice shield. It is not a warranty that the answer is correct. You still own the work product, citations, and judgment. See our approach and the FAQ on that framing.
How the sequence helps
Default order: Grok, Perplexity, ChatGPT, Gemini, Claude. Order is configurable. Later models are allowed to reject a weak premise, not only polish wording. Details: how Pingpong works.
