Plan the same trip in the same conversation
Group travel planning usually spreads across messages, browser tabs, saved posts, and one person's AI account. Someone asks the AI for an itinerary, sends a screenshot, and then discovers that another traveller has different dates, a tighter budget, or no intention of getting up at six.
A shared Unium chat puts everyone in one planning thread. Each traveller adds their own constraints in their own words, and the AI works with all of them at once instead of relying on one person to restate them.
Let the AI collect the constraints first
The useful move is to hand the awkward part to the AI. Ask it to interview the group before it proposes anything:
- Dates, arrival points, and how many people are actually coming.
- Budget per person, and who is flexible on it.
- Mobility, food, and anything that quietly rules an option out.
- The one thing each person would be annoyed to miss.
- What is already booked, and what is still just an idea.
Then let it name the conflicts. Two people wanting different departure days is much easier to solve when something neutral says it out loud on day one rather than a week before the flights.
Adding the group takes one link
Send the link by message or show a QR code. Everyone joins in one tap, on iPhone or on the web, with their own account. Nobody buys anything: one Unium subscription covers everyone on the account, from $10 a month, and getting started is free.
It keeps the plan and chases the loose ends
The thread is where the plan lives. Dates, the shortlist of places to stay, the day that is still undecided, the booking someone said they would do and has not. Ask it what is still open and it will tell you, which is usually the difference between a plan and a group chat full of links.
Use different models without rebuilding the plan
One model writes a decent first itinerary, another is better at pointing out that your third day involves four hours of trains. On a paid plan you switch between GPT, Claude, Gemini, and others while the dates, preferences, and previous suggestions stay in the same thread.
AI travel information can be incomplete or out of date. Confirm opening hours, entry rules, transport schedules, accessibility, prices, and reservations with authoritative sources before relying on them.
For a two-person trip, the shared AI chat for couples covers the same pattern with less negotiation.
