Capability Brief
Cite real. Cite right.
Sentinel Citation reads every citation in your federal filing, verifies each against authoritative sources, and tells you whether the cited authority actually supports the use you made of it.
Run it on the brief you're drafting. Or on opposing counsel's.
Your first filing is free. No card required to start.
Every citation, four checks
- ✓ Existence — the authority actually exists
- ✓ Quote Accuracy — quotes match the source
- ✓ Holding Support — the cite isn't stretched past the holding
- ✓ Citation Strength — binding, current, on-point
What the report tells you
Four checks per citation.
01
Existence
Does the cited authority actually exist? Cross-referenced against CourtListener, Cornell LII, and eCFR.
02
Quote Accuracy
Did the filing quote the authority accurately, or is the quote massaged or fabricated?
03
Holding Support
Does the case actually say what the brief says it says, or is the cite stretched past the holding?
04
Citation Strength
How strong is the citation: binding vs. persuasive, current vs. narrowed, on-point vs. distinguishable?
Two ways to use it
Offense and defense.
On your filings
Catch the AI slop before it ships.
Catch your own honest misreads too. The report flags fabrications, misquotes, and stretched holdings. Citation Strength surfaces the soft spots a clerk would find on first read.
On opposing counsel's
Stop reacting. Start hunting.
Run the same analysis on the brief they just filed. The fabrications go on your motion to strike. The weak citations go in your oral argument prep.
How it works
Three judging models. One meta-judge.
Three judging models, each from a different vendor, read your filing independently and judge every citation across the four checks. Each authority is verified against CourtListener, Cornell LII, or eCFR. A fourth model synthesizes the verdicts.
