How it works

One chat, both of you in it.

Nobody has to relay anything. This is how a shared chat actually goes.

  1. Unium opens the conversation.
  2. You say what you are stuck on.
  3. It suggests something, and checks it with the other person.
  4. They agree, add context, or push back.
  5. It goes ahead with something that works for both of you.
Our weekendYA
Unium AIHey Alex & Sam, how can I help you today?
YouWe are not sure what to do this weekend. I want to do something active, Alex says he is tired and wants to chill.
Unium AIHow about doing both: something chill on Saturday so Alex can rest, and something active on Sunday. Do you think one day of rest would be enough for you, Alex?
AlexYeah, I think so. Can we keep Sunday flexible though? Happy to book something as long as it is cancellable. Can you find us some options?
Unium AISure, let me search the web. From our past chats I know you two enjoy padel, so I will look for courts that take a short notice cancellation.

What you get

Built for two people, not one.

  • The Unium iPhone app showing shared chats at the top of the list and private chats below them

    Use shared chats to solve shared problems. Keep private matters to private chats.

    Everything you open together sits in one list you both see. Anything you would rather keep to yourself goes in a private chat.

  • The account screen in the Unium iPhone app showing one shared subscription and the two people it covers

    Do not waste your money: one subscription covers two people.

    One plan on one account, unlocked for both of you. Inviting your partner, a friend, or your family is free.

  • The model picker in the Unium iPhone app, with popular models, an automatic option, and tools like web search

    Always use the cleverest AI for the job.

    New AIs get released all the time. And all of them are always available to you. Unium picks the best AI for you, or you can pick the one you like most yourself.

Try it first

Try it on a real argument, right now.

You do not have to bring your own. Read something that actually happened to someone else, say who you think was in the wrong, and see whether the AI agrees with you. Then you can send it to the person you had your own version of it with.

Start the demoNo account, no download. It runs in your browser.

What people bring to it

The things that go round in circles.

Open a chat, say what it is in your own words, and add the person it involves.

  • We keep having the same argument about money.

    It asks what each of you actually minds about, then puts a split on the table you can both look at.

  • Neither of us can pick where to go in October.

    It asks you both what matters, researches the options, and keeps the plan where you can both see it.

  • My brother and I disagree about our mum’s care.

    A decision nobody wants to make alone. It takes both sets of worries seriously and lays out the trade-offs.

  • Three flatmates, one chore rota, no agreement.

    It works out a rota around who is actually home when, and everyone can see how it got there.

Frequently asked

Quick answers.

How does it work with another person?

Start a chat and send them the link. They join the same conversation, see the whole thread, and the AI answers both of you in it rather than in two separate chats.

Does the other person need to pay?

No. One subscription covers everyone on the account, so adding your partner or your family does not add a second bill.

Are all of my chats shared?

Chats are shared with the people on your account by default, which is what makes the AI useful between you. You can make any chat private, and a private chat is never shared back.

Do you train on my chats?

No. Conversations are not used to train models. Per-chat memory is opt-in and you can clear it any time.

Is there an Android app?

Not yet. Unium works on the web and on iPhone today, and Android is next.
