JurisBuilt in trial.
For trial lawyers.
JurisOS wasn't designed in a conference room. It was built the night before jury selection — and refined in the courtroom.
The Founder
Matthew Loker is a trial attorney and the founder of Loker Law, APC, a California consumer-protection firm. He represents individuals against banks, debt collectors, and credit reporting agencies in state and federal courts, trying cases under statutes like the Fair Credit Reporting Act and the Electronic Fund Transfer Act.
He is also the kind of lawyer who automates everything he can — pleadings, discovery, exhibit covers — so that trial time goes to strategy, not paperwork. JurisOS is the courtroom-facing product of that obsession.
Why JurisOS Exists
Jury selection is the highest-stakes, fastest-moving part of any trial. Panelists rotate through the box while you juggle questionnaires, seating charts, strike counts, and challenge grounds — traditionally on sticky notes and legal pads. Miss one detail and you burn a peremptory you needed, or seat a juror you should have challenged for cause.
Preparing for his own jury trial, Matt built a live dashboard instead: every juror on a card, the box laid out the way the courtroom is, strikes and challenges logged to the second with the controlling authority one click away. It worked so well in trial that other lawyers started asking for it.
That dashboard became JurisOS — the trial operating system. One tool, one screen, everything voir dire.
The Philosophy
Software for trial lawyers should work the way trial works: offline-capable, zero learning curve at counsel table, and priced per trial — not as a subscription you pay for twelve months a year to use one week of it.
Two live demos.
Zero setup.
Click into either demo below and run a full mock jury selection — like, dislike, strike, and challenge. All juror data is fictional. Nothing to install.
Questionnaire Mode
When the court gives you juror questionnaires, JurisOS turns them into searchable juror cards — age, city, occupation, employer, and issue tags (prior lawsuits, damages feelings, subject-matter experience) surfaced right on the card. Click any juror to review their full questionnaire answers without touching a binder.
Live-Capture Mode
No questionnaires in your courtroom? Live-capture mode gives you blank juror cards you fill in at counsel table as the panel answers — name, background, and your notes, captured in seconds while voir dire moves. The box, the venire, and your strike counts stay live the entire time.
State & Federal — The Box Matches Your Courtroom
JurisOS is built for both systems. The federal demo above seats an 8-juror box; the state demo seats 12 jurors plus alternates. Seat count, alternate slots, and peremptory allotments are all configured to your jurisdiction — 3 per side in federal civil, 6 per side in California state court — so the dashboard counts down exactly what you actually have left.
Challenge Authority, Built In
Every strike is logged to the second, attributed to a party, and tracked as granted or denied. The challenge tracker cites the controlling authority for your jurisdiction — 28 U.S.C. §§ 1865 & 1870 and the federal for-cause case law in federal court, CCP §§ 225–231 in California state court — so when the judge asks for your grounds, they're already on screen.
Juror Review, One Click Deep
Click any card and the full questionnaire opens in place — every answer, plus your like/dislike rating and a strike/challenge button right in the modal. Edits and notes save automatically to your browser; nothing leaves your machine.
Completely Customizable
Every dashboard is built for your case and your firm. Swap the interface to your firm's colors, put your caption and courtroom in the header, rename the issue tags, and change what appears on each juror card. If you want it in there, it goes in there.

One trial.
One flat fee.
You go to trial a few times a year. You shouldn't pay for jury-selection software every month you're not picking a jury.
Why No Subscription
Subscription pricing makes sense for software you use every day. Voir dire isn't that. JurisOS is priced like the trial tool it is: $1,000 per dashboard, paid once, for the trial you're actually in. When your next trial comes, we build your next dashboard.
Every dashboard is prepared for your specific case — caption, court, jurisdiction rules, questionnaires if you have them — and delivered ready to open at counsel table, no install and no account.
The jury is
still out.
JurisOS is fresh out of its first trials. Verbatim verdicts from the lawyers who used it are being collected now.
