pingpong

Catch the risk before you commit. pingpong runs one high-stakes question through five flagship models in sequence: Grok, Perplexity, ChatGPT, Gemini, then Claude. Each step can challenge your premise or the prior answer instead of rubber-stamping it.

Built for founders, executives, consultants, investors, lawyers, product managers, and teams who do not trust a single AI answer on a decision that matters.

Plans

Your first eligible web review is free. Further web reviews need a subscription. Web Plus is $19.99/month. Web Pro is $124.99/month. On iOS the listing shows three free pingpongs, then Plus at $24.99/month or Pro at $59.99/month. Full table and checkout: pricing.

Before you commit

Most bad commits already look finished on the screen: an offer letter, a price change, a launch note, a DocuSign packet, a partnership term sheet, a raise deck, an acquisition thesis. The finger is hovering. The before you commit hub indexes short pause rituals for those irreversible moves, so you run the five-model chain once before Send, Publish, or Countersign.

Dispute cases

Use pingpong to review a merchant dispute narrative and identify facts to verify. The PDF form formats supplied text and evidence descriptions; it does not attach source documents or submit a response to a processor. The PDF API supports an eligible browser preview and business API access, separate from web review subscriptions. Start with the dispute guides for case preparation and evidence checklists.

Adversarial decision review

When the plan already has a name and you want later labs to lean on it, the adversarial decision review hub indexes pressure-test, second-guess, hole-finding, red-team, and related money pages so you pick the phrasing you already use, then run the five-model chain once.
