How TabiTabi works.

Start from the main action on the home page. When the new-trip form opens, almost all of it can wait.

Only the name is required. Destination and dates are optional — a trip can stay a draft for as long as the idea does. Dated trips can run up to 1,000 days.

Pick the base currency with care. Every budget total is shown in it, and it locks once the trip has its first expense, because every stored amount and exchange rate is denominated against it.

Solo is the default. The primary traveler starts as you. There is no party-size question — add companions only when you need them.

Statuses take care of themselves. Draft, upcoming, or past comes from the dates; the pill on each trip card updates on its own.

The itinerary tab holds anything with a time and place — or without one: flights, lodging, transport, activities, food, drinks, shopping, and everything else.

Dates and times are optional. Undated items wait under Unscheduled. Dated items group into their days, where you can reorder them with the arrows or sort a day by time.

Flights and transport go between places. They take From and To instead of a single place, and the flight fields search real airports. Picking a suggestion pins that airport's code to the item; free text stays free text.

One record can span days. Lodging takes a check-out date and appears across the stay; a flight or transport that arrives on a later day shows an arrival card there. Every one of those cards is the same record — edit it anywhere.

Costs attach where they happen. Add a cost from an item’s Edit dialog and it is saved as an expense linked to the item: description, category, and date start from the item and stay editable there or from the Budget tab.

The budget tab is one ledger shared with the itinerary — expense by expense, in whatever currency the money was actually spent.

Any currency, one base. A foreign-currency expense takes an exchange rate, prefilled from a public rate source and editable before saving. The saved rate never changes on its own, and the original amount always appears first with the conversion beside it.

Unit price times quantity. Four nights or six tickets are one expense with a quantity, not six entries.

Split it three ways. Equal divides the total among the travelers you check, individual hands it to one person, and custom takes exact amounts that must add up to the total.

Paid by is optional. Record who fronted the money when it helps; skip it when it doesn't.

Summaries stay live. The trip total, each traveler's allocated responsibility, and a by-category breakdown are always current, all in the base currency.

Travelers are who the costs are split between. Add or rename them on the People tab; the Travel party card sits beside every trip.

Add companions when they matter. A trip supports up to 10 travelers, and each traveler's number on the budget tab is the share allocated to them.

Your colour is yours to pick. Everyone in the party gets a colour, and it is how the itinerary, the budget, and the split rows tell one person from another. Select your own dot in the Travel party card to change it. You can change only your own — a colour someone else is already wearing is shown faded and cannot be taken.

Removing someone is deliberate. The first traveler anchors the trip and stays. Anyone else can go once nothing points at them — no share of an expense, no itinerary item assigned to them — and the People tab says which of the two is still in the way. Removing then takes a typed confirmation, the same as deleting a trip.

An empty Day 1 is the hardest part. The Ideas tab turns a few choices into a rough day-by-day plan you can pull pieces from.

You pick from menus, not a prompt box. Choose one of the trip's own destinations, how many days, who you're travelling with, your pace and spending level, whether each stop should come with a start time, and up to six interests. There is nothing to type. Google receives those choices and, when the trip has a start date, its month; it does not receive the trip's name, notes, itinerary, budget, or travelers.

Nothing is added until you say so. Suggestions are just a list, in the order the day is meant to run. Start times are left open unless you asked for them, so a suggested day is a shape to follow rather than a schedule to keep. Add on one opens the ordinary new-item form with the details filled in, so you can change anything before saving.

They wait for you, until the browser tab closes. Switching to another tab or reloading the page keeps the suggestions you already have, because getting them back would cost another of the day's runs. They live in that one browser tab and never reach your trip: close it, or sign out, and they're gone. Only what you saved stays.

Treat it as a starting point. The suggestions come from Google Gemini and are generated text: a place may have closed, moved, or never have been quite right. Check anything that matters. There is a daily limit, shared across the site, so a run may sometimes have to wait until tomorrow.

The People tab is part of every trip. After you sign in, it also shows which people have accounts and any invitations.

Invite with a link. Owners send an Editor or Viewer link from the row of the person it will seat. Anyone who has a live link can join with the access it grants — the link is the invitation, so treat it like a key and revoke it to stop it working.

Three roles, one extra switch. Owners have full access, including trip details, sharing, and deletion. Editors shape the itinerary and travelers. Viewers read. Expense editing is granted separately, so an editor can plan without touching money — or a viewer can manage money without touching plans.

Members plan, travelers split costs. Joining through a person's link makes you a member and links your account to that person's place in the party, including their share of the costs.

Leaving and handing over. Any member except the owner can leave a trip. Their person and share of the costs stay in the party while their account is unlinked and loses access. An owner hands the trip over by making someone else an owner — the new owner can then change or remove the old owner's access. Or delete the trip, which removes it for every member.

TabiTabi shows you what it does before you sign in, and keeps what you plan once you do.

Signed out, you get an example. A fresh signed-out app starts with one example trip, there so the planner has something to show. A browser may also keep trips made with an earlier version. Everything shown while signed out stays in this browser and is never carried into an account. When a foreign-currency expense needs a rate, TabiTabi sends only the trip's base-currency code to the public rate source.

Sign in to plan your own. Planning a trip of your own starts with signing in. Account trips sync to every member's devices, and they are the only trips TabiTabi stores for you.

Deleting is deliberate. Deleting a trip takes a typed confirmation, and it cannot be undone.
