Onsen Mirador

A geothermal bathhouse of six pools cut into basalt, open in three-hour sessions with a maximum of forty bathers. There are no treatments, no music and no phones past the lockers.

Steam, dark water, a serif that whispers. Best mood on the sheet.

The brief the agent was handed

What it was asked for.

Audience

City workers booking a three-hour reset, not a full spa day

The pitch

Onsen Mirador is a geothermal bathhouse with a strict silent-bathing policy, sold in three-hour sessions with no treatments and no phones. The page is a split-screen scroller pairing each pool with the exact temperature and what it is for.

Sections it decided on

  1. Split hero: steam over water and the silence rule
  2. The six pools, each with temperature and purpose
  3. The circuit: how to move through it in three hours
  4. Silence, nudity and phone policy, stated plainly
  5. What we do not have: no treatments, no bar, no music
  6. Session times and how few people are in at once
  7. Accessibility, and what we can adapt
  8. Reserve a session

The run

Fifty of these. About one developer day.

Same toolchain, fifty different briefs, no templates. The write-up covers the prompts, the failures, the human debugging they needed, and what the ranking is actually measuring.

Fictional demo

Every one of these fifty businesses is invented. The pages, and all the text, statistics, prices, reviews, people and images on them, were generated by AI as a design demonstration. Nothing here is a real offer, a real endorsement, or professional advice. Full notice
