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.

  • Share AI chats

    Most AI chats are stuck inside a single account. In Unium a chat is somewhere two people stand together: the other person reads the whole thread, adds their side, and the AI answers both of you in it.

  • Every model in one app

    Different models are good at different things. Unium puts the leading ones in a single app, so you can pick the right one for each question without juggling tabs, logins, or a subscription per provider.

  • Shared AI trip planner

    Give every traveller a voice in the same planning conversation. Dates, budgets, constraints, and ideas stay in one thread while the AI researches, names the conflicts, and chases the loose ends.

  • Shared AI chat for couples

    A shared chat gives both partners the same history and space to speak in their own words. The AI asks each of you for your side before it suggests anything, so nobody has to be the messenger.

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.

Will the AI take sides?

No. It asks each of you for your side before it suggests anything, and it keeps track of who said what, so it weighs both accounts instead of agreeing with whoever typed last. If it gets the balance wrong, say so and it adjusts.

What if my partner is not ready to join?

Start on your own. Work out what you want to say, and how, in a private chat. When they are ready, start a shared chat and send them the link. They join in one tap.

Does Unium replace couples therapy?

No. It is for the argument, plan or decision in front of you, and for the days between sessions. When something needs a professional it says so, and couples have used it to choose a counsellor and to keep working on what the sessions gave them.

Can I import a WhatsApp chat or a ChatGPT conversation?

Yes. Export a WhatsApp chat and pick Unium in the share sheet, or paste a ChatGPT share link into a chat, and Unium reads what was actually said.

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?

Yes. Unium is on Google Play, with notifications. Same account, same chats.

Does Unium work for business?

Yes. Plenty of people use Unium for work. For teams, we also make Drephos, a product built specifically for businesses.
