Claude tests. Codex tests.
They argue. Gemini judges.
Any AI can find the obvious bugs. The real ones hide in the disagreements. Three AI agents independently test your app, then we force them to argue it out until only the truth survives.
Three steps. Zero scripts.

Two AI agents — Claude and Codex — independently test your app like real users. No scripts, no selectors, no setup.
They disagree
We force them to argue it out. Each model sees the other's findings and must defend their position or concede. Up to 2 rounds of cross-examination.
You get the truth
Confirmed bugs, discovered edge cases, and zero false positives. Every finding earned its place through adversarial scrutiny.
The 2ndOpinion Advantage
Bugs that survive cross-examination from two of the world's most powerful AIs aren't opinions — they're facts.
