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
Trial moves faster than paper. Panelists rotate through the box while you juggle questionnaires, seating charts, and strike counts; exhibits fly at witnesses while you track objections, rulings, and what actually made it into evidence — traditionally on sticky notes and legal pads. Miss one detail and you burn a peremptory you needed, waive an objection on appeal, or lose the quote your closing was built on.
Preparing for his own jury trial, Matt built a live dashboard instead. Jury selection worked so well on it that the exhibit side of trial got the same treatment. Those two dashboards became JurisOS — the trial operating system.
The Box runs your jury selection. The Record runs your exhibits. One screen each, both built for counsel table, and on matters running both, one click switches between them — one site, not two.
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.
The Box.
Every seat. Every strike. Time-stamped.
The Box is JurisOS's voir dire dashboard: the venire on cards, the box laid out the way your courtroom is, and every challenge preserved with its grounds and authority. All juror data below is fictional.
Questionnaire Mode
When the court gives you juror questionnaires, The Box 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.
Rate The Panel As It Moves
Every juror carries a −5 to +5 star rating, and the card border color-codes instantly — green for keeps, red for targets — across the box and the entire venire. When panelists rotate into the box, you already know how you feel about who's coming.
Juror Review, One Click Deep
Click any card and the full questionnaire opens in place — every answer, plus your rating and a strike/challenge button right in the modal. Edits and notes save automatically; nothing leaves your machine.
Record A Challenge In Seconds
When you move to strike, the challenge dialog captures everything the record needs: challenging party, for-cause ground or peremptory, the court's ruling, the time to the second, and your basis — with the controlling authority for each ground printed right on the option. Say it to the judge, click it, done.
Challenge Authority, Built In
Every strike lands in a time-stamped log, attributed to a party, tracked as granted or denied, with peremptories counted down per side. The 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.
The Strike Sandbox
Before you burn a peremptory, game it out. The sandbox simulates removals — for cause or peremptory, by either party — and shows you who rotates into the box next, without ever touching the live board. Set a target juror and see exactly what it takes to get them on the panel.
State & Federal — The Box Matches Your Courtroom
The Box is built for both systems. The federal build above seats an 8-juror box; the state build 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.
The Record.
Every exhibit. Every objection. To the second.
The Record is JurisOS's exhibit dashboard: your exhibit list as a visual board, your witnesses on a clock, and a record built for appeal while you try the case. All case data below is fictional.
The Stand — Witnesses On A Clock
Call a witness and the clock starts. Every examination segment is attributed to the side asking — direct, cross, redirect — with breaks kept off the clock, per-witness totals, and a running tally of examination time per side. When the court allocates trial hours, you know exactly where yours went. Closing notes and key quotes pin to each witness the moment they say them, tagged Quote, Admission, Impeachment, or Theme.
Your Exhibit List, As A Board
Upload the exhibit list and the exhibits: every exhibit becomes a card — numbered from your list, with a preview image of the actual document, its Bates range, and its live status. Introduce an exhibit through the witness on the stand and it's stamped to the second; green means admitted, red means excluded, gold means an objection is waiting on a ruling. Exhibits can come in through multiple witnesses, and the board tracks every introduction.
Search Inside Every Exhibit
Can't remember which exhibit has the phrase you need? The full text of every exhibit is baked into the board — including scanned documents, which are OCR'd — so one search finds every exhibit containing your words, with hit counts and highlighted snippets right on the cards. Mid-cross, "verified as accurate" is three keystrokes away from the document that says it.
Objections Preserved, Rulings Captured
An objection not asserted is waived — so The Record makes asserting it effortless. Log the objecting party and grounds in two taps, then rule it Sustained, Overruled, or Reserved right from the card the moment the court speaks. Every exhibit keeps a complete timeline — every introduction, every objection, every ruling, every disposition, time-stamped — and any correction is logged on the record too.
The Report Writes Itself
At any recess, generate a branded exhibit report — by witness, by several witnesses, or the whole case — sorted by witness then exhibit number, with introduction times, objections and rulings, dispositions, your closing notes, and per-witness examination time. Print it, save it as a PDF, or export CSV for Excel.
One Trial, One Site
Running both products? They live on one matter site with a single click between them — The Box for the morning you pick the jury, The Record for every day after. Same login, same screen, no juggling websites in front of the judge. Both dashboards work offline at counsel table and sync live between co-counsel when connected.
Completely Customizable
Every dashboard is built for your case and your firm — your caption, your court's rules, your party labels (state, federal, or arbitration), your firm's colors. If you want it in there, it goes in there.
Want To Drive It Yourself?
The screenshots are the tour — the live demo is the test drive. Book a walkthrough and we'll run a mock jury selection and a mock examination together on live dashboards, with all-fictional data. Video walkthroughs are also in production.
One trial.
One flat fee.
You go to trial a few times a year. You shouldn't pay for trial software every month you're not in trial.
Why No Subscription
Subscription pricing makes sense for software you use every day. Trial isn't that. JurisOS is priced like the trial tool it is: $1,000 per product, per trial — or $1,500 for both — 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, exhibit list, questionnaires if you have them — and delivered ready to open at counsel table, no install and no account.
