Guides
Find the way you want to use AI.
Start with something you are actually trying to sort out. Each guide walks through one situation, with the other person in the chat.
Start here
How a shared chat works, how to add someone, and what stays private.
- Import a WhatsApp chatExport the chat from WhatsApp, pick Unium in the share sheet, and choose the chat it goes to. It takes about a minute, and the assistant then reads what was actually said.
- Every model in one appDifferent 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.
- Share AI chatsMost 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.
- Two people, one AI chatYes, and it is the whole idea. A Unium chat is one live thread that two or more people read and continue, each from their own account, with the AI working between you rather than for one of you.
Solve something together
One situation at a time, from trips and bills to the argument you keep having.
- Shared AI chat for couplesA 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.
- Settle an argumentForwarding an AI answer to someone you are arguing with settles nothing: they never got to talk to it. Put both of you in the same thread and let it hear each side before it says anything.
- Split the household billsHalf of the bills can take very different shares of your pay. Start with what each of you can afford, compare a few ways to split the shared costs, and agree what you want to try.
- Plan a move togetherTwo people moving house are solving a logistics problem and a negotiation at the same time. A shared chat handles the second one first, then runs the countdown for you.
- Helping a parent decideThe hard part is rarely the research. It is keeping your parent in the conversation and a sibling in the loop without turning yourself into the person who decides.
- Decide between two optionsAsk a friend and they get one side of the story. Ask an AI alone and it agrees with your framing. Put them in the same conversation and you get something neither gives you on its own.
- Shared AI trip plannerGive 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.
- Talk through a long-distance relationshipA missed call can mean different things to each of you. Before arguing about how often you text, compare what contact you need, what your schedules allow, and what you are working towards together.
- Co-parenting after separationYou may no longer be a couple, but school runs and changed plans still need an answer. Start with one practical request and a written record you can both check.
- Couples with different first languagesThe person speaking a second language should not have to give up the detail of what they mean. Let each person write in the language they know best, then check the meaning together.
Compare your options
See how Unium differs from single-provider apps and group chats.
- ChatGPT group chat alternativeChatGPT stopped people creating or joining new group chats on 9 July 2026. Unium gives partners, families, and friends a shared AI thread they can continue together, with the AI running it rather than just answering whoever typed last.
- A ChatGPT alternativeChatGPT is a great default. But it is one company’s models, on your account alone, billed one person at a time. If any of those three things rubs you the wrong way, here is what Unium does differently.
- Unium vs PoeBoth put people and several AI models in the same chat. Poe is broader, with groups of up to 200 and an enormous bot catalogue. Unium is narrower: shared conversations for couples, families, and friends, with one plan covering the account.
