Unium
Collaborate in a group chat
Invite your partner, friend or family into the chat with AI. Let others talk to your AI too and let it facilitate your shared discussion.
Keep privacy
Your own chats stay private and are never shared with anyone else.
Share subscription
You can add up to 10 people to your subscription. You are in control, so you can see usage, add or remove people at any time.
Use the best AI model
New AI models get released all the time. You can use any of them, without losing memory or context.
How it works
One chat, both of you in it.
Nobody has to relay anything. This is how a shared chat actually goes.
- Unium opens the conversation.
- You say what you are stuck on.
- It suggests something, and checks it with the other person.
- They agree, add context, or push back.
- It goes ahead with something that works for both of you.
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.
Read the guideEvery 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.

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.
Read the guideShared 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.
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 available on Android: tap Install on Android and it goes on your home screen, with notifications. Same account, same chats.
