Adversarial itinerary planning

Two agents argue.
You get the better trip.

Pick a destination. Watch a slow-travel romantic and a hyper-efficient planner clash over every hour of your day. Keep the version you like best.

How it works
The Flaneur and The Completionist debating a travel itinerary

Different philosophies. Same trip.

The Flaneur

The Flaneur

Slow travel

"Leave room for the street that catches your eye. The best meals are never on the list."

  • Prioritizes atmosphere over checkboxes
  • Blocks long stretches for wandering
  • Favours local haunts over tourist staples
The Completionist

The Completionist

Max efficiency

"Every hour has a purpose. If you're walking past a landmark, you're stopping."

  • Packs every slot with high-signal stops
  • Optimises routes for proximity
  • Never leaves a top-5 sight off the list

Three rounds. One itinerary.

1

Set the stage

Enter a destination, pick your trip length, and choose which model powers the debate. Hit plan.

2

Watch them clash

Each agent proposes, critiques, and refines. A neutral arbitrator merges their best ideas. You can inject your own preferences mid-debate.

3

Pick your winner

Scrub through every version, see what changed, read each agent's reasoning, and lock in the itinerary that fits your style.

Sign in to start debating

Your sessions persist. Your debates stay linked. Every version stays revisitable.
