Courts are done being patient with fake citations. A public database now tracks more than 1,600 court matters involving AI hallucinations, and the penalties have grown teeth: six-figure sanctions, fee forfeitures, attorney suspensions. Judges are reading the authorities by hand. Existence checks answer one question. A filing rests on more than one.

Sentinel Citation reads every citation in your federal filing and puts each one in front of a jury: three AI models from rival vendors, with a fourth as judge, checking against real court records like CourtListener, Cornell's LII, and the eCFR. Every citation is graded on four questions:

Does the authority exist?
Is it quoted accurately?
Does it support the point it's cited for?
How strong is it?

Every use is graded on its own, so the same case can score solid in one paragraph and get floored in the next. And the report shows the jury's reasoning, never a black-box score.

Sentinel Citation is triage, not a verdict. It saves the hours; the lawyer makes the calls. Run it on your draft before you sign it. Run it on the other side's brief and see what holds up.
