Reus excipiendo
fit actor

The defendant, by raising an exception, becomes the plaintiff.

In Roman law, the exceptio was the defendant's shield—a procedural mechanism to deflect prosecution by revealing what the state overlooked.

It wasn't passive defense. It was strategic reversal. The act of defending became the attack.

That's what we built. AI that doesn't just analyze—it finds the exceptio.
