The two kinds of argument

Most arguments are one of two things, and they need opposite treatment.

Some are factual. Who actually said that, how long the drive really takes, whether the thing you both half-remember is true. These end the moment somebody checks, and the only reason they drag on is that neither of you wants to be the one who looks it up.

The rest are not about facts at all. You want different things, or you want the same thing for different reasons, and no amount of evidence settles it. What those need is someone to hear both sides properly and say what they think.

A shared AI chat is unusually good at both, for the same reason: it is the only participant with no stake in who wins.

Put both of you in the same chat

Start a chat, send the link, and the other person joins in a tap. From there the AI runs it. It asks each of you what happened or what you want, in your own words, without the other person interrupting. It knows who said what, so it can weigh two accounts rather than the loudest one.

Then ask it directly. Not "who is right" as a gotcha, but the question you actually want answered:

  • Check the fact and show where it comes from.
  • Lay out the strongest version of each side, then say which one it finds more convincing.
  • Point out where you are arguing about different things without noticing.
  • Suggest something you could both live with, and say what each of you gives up.

The last one is the useful one more often than people expect.

Why it beats screenshotting one to the other

If one of you asks an AI on your own and forwards the answer, you have not settled anything. You have introduced a witness the other person did not get to talk to, and they will say so, correctly.

When both of you are in the thread, that objection disappears. Everyone saw the question. Everyone saw the answer. And if the AI got a detail wrong, either of you can correct it in the same conversation instead of arguing about the screenshot.

Nobody has to buy anything

Send the link, they join on iPhone or the web with their own account. One Unium subscription covers everyone on the account, from $10 a month, and getting started is free on a model we choose for you.

On a paid plan you can also change the model mid-argument, which is worth doing when one gives an answer that sounds like it is trying to keep everybody happy.

Where to stop

It is good at facts, framing, and fair summaries. It is not a mediator with a professional duty to either of you, it does not know what happened in the room, and it should not be the thing that decides something serious about your relationship. Use it to get unstuck, not to hand over the decision.

For the pattern rather than the one fight, see the shared AI chat for couples.
