Type the exhibit number. Press Enter. The exhibit is on the courtroom display — and nothing else is.
Windows and macOS · Works with the network cable unplugged · Built for prosecutors and defense attorneys, not litigation-support departments
Type an exhibit number below, or click one in the list. Watch what happens when you ask for one the court has not admitted.
Press Esc to blank the display, exactly as you would in court. Images shown are synthetic sample evidence.
Kairos runs two windows. One is yours. One is the jury's. They are separate programs, so a fault in the first cannot put anything on the second.
The full evidence list, admitted or not. Search, notes, witness outlines, exhibit numbering, and every technical message Kairos produces. You work here freely.
One exhibit at a time and nothing else. No desktop, no taskbar, no notifications, no filenames, no error dialogs, no software branding. If the program faults, it goes black.
Any presentation tool can show a photograph. The reason to choose one for criminal trial is what it will not show. These are guarantees, and each is enforced by an automated test that runs on every build.
Kairos is not a discounted litigation-support platform. It is a courtroom tool for lawyers who run their own trials.
Type the number, press Enter. Alphanumeric exhibits like 12A, P-12 and Defense A work, and are never confused with one another.
Mark exhibits admitted as the court rules. Only admitted evidence can be published, and status changes take effect instantly.
Drag in a discovery folder. Kairos copies everything locally, fingerprints it, and flags probable duplicates without deleting anything.
Body-camera, surveillance and interview-room exports, played through a VLC-class engine rather than whatever codecs the machine happens to have.
Pause, precise seek, frame stepping, variable speed and mute — the controls you actually use while a witness is describing what happened.
One key blacks out the courtroom. Hide keeps the exhibit loaded so bringing it back is instant, and stops the audio at the same time.
Office documents converted on import, pages presented with the same controls as photographs. No copy of Word required.
True high-resolution zoom that stays sharp, plus highlights, arrows, callouts and freehand marks composited over the exhibit, never burned into it.
Pin a page, a crop and a set of annotations as a reusable view, ready to recall in closing without rebuilding it.
Two exhibits on the courtroom display at once, for the comparison that makes the point better than any argument.
Sequence the exhibits for each witness, with your examination outline beside them on your screen only. Step out to another exhibit and return without losing your place.
A slide builder scoped to argument: text, exhibits, clips and callouts, with presenter notes. Jump to an exhibit and come back to the same slide.
Available means shipping in the current preview build. In build means specified and under development for version 1. We would rather label the difference than blur it.
Evidence is copied into the case on import. Unplug the drive, lose the network, and the exhibit still appears.
Work is saved continuously and the case is written transactionally, so a forced shutdown costs you the last few seconds, not the trial.
Offline entitlement with generous grace. A licence check will never be the reason an exhibit does not appear.
Runs under your existing sign-in, BitLocker, endpoint policy and device management rather than a parallel identity system.
Encrypt a case at rest for sealed or sensitive matters, with the key held by your organisation.
No evidence, filenames or case metadata leave the machine. A prosecutor should never have to explain why the software phoned home.
Presentation software is usually licensed per seat at a price that forces an office to share a handful of copies. That is backwards. The lawyer who needs it is whoever is in trial that week.
Solo practitioners and independent trial consultants.
Small criminal-defense firms and rural prosecutor offices.
District attorney and public defender offices, allocated by seat count.
Statewide systems and large agencies, with volume activation and managed deployment.
Pricing is being set now and will be published before general release. If you want to influence it, tell us the size of your office when you request access.
No, and it will not become one. Kairos starts once you already have the evidence. It does not manage discovery, chain of custody, deadlines or your practice. Those products exist and are not what a lawyer needs while standing in front of a jury.
Entirely. Opening a case, playing media, recalling exhibits and licensing all work with the machine offline. Courtroom Wi-Fi is not a dependency we are willing to accept.
Photographs and common images, video and audio including the awkward exports from surveillance DVRs, body cameras and interview rooms, and documents. Media plays through a VLC-class engine so you are not dependent on what codecs the machine happens to have.
A case is a self-contained folder, so it copies. Packaged export and import with integrity checking is on the version 1 list.
No. That is close to the whole point. If you can type an exhibit number you can run Kairos, and the essential workflow takes about ten minutes to learn.
Both. Windows is the primary target because that is what most offices deploy, and the macOS build runs from the same codebase.
Preview. The courtroom loop — import, number, admit, recall, present, blank — works today and is what early testers are using. The features marked "in build" above are specified and under development. We will keep that distinction honest on this page.
We are looking for prosecutors and defense attorneys willing to put a preview build in front of an actual courtroom display and tell us where it falls short. No cost, and no obligation.
