Plan a trip with AI — and keep the whole plan in one place

A real trip is several jobs. You look up flights in one chat, ask another about neighbourhoods, plan the days in a third, and work out the budget somewhere else. A week later you cannot remember which chat had the hotel shortlist, and the new chat has never heard that you are travelling with a toddler, or that you already ruled out Sunday flights.

Every time you open a new conversation, you explain the trip again — and every time, something gets left out.

1. 1
   Start a project in PassTheBrief — for example, “Lisbon long weekend”, with the dates and who is going.
2. 2
   Press Copy the planning request and paste it into any assistant. It asks you a few questions first — budget, pace, what you love and what you would rather skip — then writes the plan.
3. 3
   Paste its whole reply back. The plan becomes a list of tasks, each with the assistant that suits it and a ready-made prompt.
4. 4
   Work through the tasks in whichever assistant you like. Paste each answer back, and the flights you found, the shortlist and the itinerary are saved under the right task.

For a long weekend in Lisbon, a plan might come back like this:

Lisbon long weekend — 15 to 18 May, two people, about $1,800

1. Find flights that land by Friday lunchtime
   Best AI: Perplexity
2. Choose a neighbourhood to stay in
   Best AI: ChatGPT
3. Shortlist three places to stay in that area
   Best AI: Perplexity
4. Plan the three days, one area per day
   Best AI: Claude
5. Make the budget, with a buffer
   Best AI: ChatGPT
6. Book the flights and the stay
   Best AI: you

Each task comes with a ready-made prompt, so whichever AI does it
gets the dates, the budget and what you have decided so far.

When you decide something — “stay in Alfama”, “no early flights” — record it as a decision, and every assistant you hand the trip to later sees it.

• Check prices and opening times yourself. AI assistants can be out of date or simply wrong. Treat their answers as a strong first draft, and confirm on the airline or booking site before you pay.
• Fix mistakes where they happened. If a later check finds the budget was added up wrong, add a correction to that task. It shows above the original work wherever the task appears, and the work itself is kept.
• PassTheBrief does not book anything. It keeps the plan and the work; the booking is yours.
