Planning
Plan the whole trip by chatting. Tell Yaycay your crew, your dates and your must-dos, and it builds a day-by-day holiday around each child, with every meal allergy-checked. Change your mind out loud and the plan reshapes.
You plan it. You pack it. You carry it. You are also, technically, on holiday.
Yaycay exists for the parent who is the itinerary. The mental load, lifted.
One app, two modes: planning, then travelling.
Yaycay does the part before you go and the part while you are there. Most planners stop at the airport.
Travelling
On the ground, Yaycay travels with you. Ask what is good to eat near here, pull a rain plan in one tap, reshuffle a tired afternoon. The flags and checks follow you all the way to the table.
Conversational, and connected
You plan by talking. With the AI you already use.
Yaycay is a conversation, not a form to fill in. And if you already pay for ChatGPT, Claude or Gemini, connect it: the whole Yaycay family layer, per-child days, allergy checks and the kids' journals, runs on top of the assistant you already know, for less.
- Just chat. No forms, no menus to wrangle, no blank page.
- Bring your own AI: connect ChatGPT, Claude or Gemini.
- The family layer rides on top: per-child plans, allergy flags, the keepsake.
Works with
Nobody sees the work. We will list it anyway.
- Researching whether the laksa place can do dairy-free.
- Holding the backup plan for the backup plan.
- Knowing the museum shuts at four on Tuesdays.
- Being asked "what are we doing today?" by four people who could, in theory, also read.
- Re-planning Thursday at 11pm because the forecast changed.
- Remembering which child is currently refusing which food.
- Booking things in a timezone you have not adjusted to yet.
Hand it over. Piece by piece.
The twenty research tabsOne chat that already knows your family.
The restaurant vettingAllergy flags, checks and reminders on every meal suggestion, with the reasoning shown, so you stay in control.
The "what if it rains"A contingency attached to every day before you leave.
The being-the-itineraryEveryone can see the plan. You are no longer the app.
The 11pm re-planTell Yaycay what changed. The plan reshapes itself.
The bored-kid emergenciesEach child has their own adventures, built for their age, before boredom gets a vote.
The grown-ups command centre
Your side of the app. Behind one PIN.
Yaycay has two views. The kids live in Explorers: their adventures, their journal, their rewards. You get the Grown-ups view, opened with a simple four-digit PIN the kids never see. It holds the part of the trip that is yours to carry.
- The full plan: bookings, times and logistics, in one place.
- The safety view in full: every note shown to you, not the kid "ask a grown-up" cue.
- The allergy and EpiPen protocol, with the dietary flags for your crew.
- The grown-ups guide and checklist, packing and documents.
- Manage every profile: add a child, set their age band, let it grow with them.
Seven people, three dietary needs, one nana who naps at two.
Big mixed groups are where family plans usually fall apart. They are where Yaycay starts.
Tell Yaycay everyone who is coming: the toddler, the teenager who claims to hate everything, the grandparents and what their knees can manage. The plan balances energy levels across the group, splits the day where it helps (teens to the climbing wall, nana to the gardens, everyone back together for dinner), and carries every dietary need in every meal suggestion. You stop being the diplomat. The plan does the negotiating.
And on the trip itself, you get to be present.
That is the actual product. Not the itinerary, not the app. The version of the holiday where you are at the table, in the pool, in the photo, because the answers are handled. Parents tell us the strangest part is the quiet: nobody asking you what is next, because everyone already knows.
