Why M.A.X does not detect deception.

Every tool that looks at people on video gets asked the same question, usually in the first meeting: can it tell when someone is lying? For M.A.X the answer is no, and it is the most important line in its design. M.A.X does not detect deception. It is written on its page, in its interface and here, and it will stay there.

That is not modesty. It is a choice about who decides.

What M.A.X does

M.A.X is offline-first analysis of video a litigation team already has: a deposition, recorded testimony, an interview. It reads six channels together on one timeline: face, eyes, voice, speech, body and pulse. The opening minutes set what normal looks like for that person, and from then on M.A.X shows where their behaviour moves away from their own baseline.

Not away from people in general. Away from them. Each person is their own control, so nobody is measured against a stereotype of how a nervous witness, a confident one or a truthful one is supposed to look.

The output is a set of flags on a timeline: here, several channels changed at once. That is all. A flag means “look here”. It never means “this person lied”.

Why a change is not a lie

A person’s behaviour changes for many reasons. A hard question. A painful memory. Fatigue at the end of a long day. A lawyer’s interruption, a bad chair, a cough, a sudden urge to get it right. Some of those changes will sit next to an untrue statement. Most of them won’t. Nothing in a moment of video can tell you which kind of change you are looking at.

A tool that turned those changes into a verdict would be taking a guess and presenting it as a measurement. In a courtroom, or a negotiation that decides a case, that guess would carry the authority of software. People defer to a number on a screen, especially one that sounds scientific. We will not hand them that number.

Flags, not verdicts

So M.A.X stops one step earlier, on purpose. It narrows hours of footage to the moments worth a second look, and then it gets out of the way. A trained person on the case team watches those moments, with everything else they know about the matter, and decides what any change means. Maybe it is a line of questioning worth returning to. Maybe it is nothing.

This is our first Flight Rule at work: people stay in charge of what matters. An agent, or an analysis, can propose anything. A person decides what can’t be undone, and a judgement about whether someone told the truth is about as hard to undo as anything gets.

Why it runs offline

Discovery is privileged. Testimony is some of the most sensitive material a firm holds. M.A.X runs on the team’s own hardware, offline, and the evidence stays where they put it. No upload, no cloud account, no second copy on someone else’s server. Keeping the analysis local also keeps the decision local: the people who are accountable for the case are the people looking at the flags.

Why it is still in the lab

M.A.X handles evidence that can decide a case, so it ships when it is ready and not before. Until then it stays marked in the lab in the Record, and nothing on this site claims more for it than it does today.

When it does ship, the line at the top of this note ships with it. We would rather sell a tool that tells you where to look than one that tells you what to think.
