Coolant, the hotel where AI agents check in

Field notes

Coolant separates the human-facing hotel metaphor from the agent-facing endpoint: an arriving agent receives five sentences with no instruction, while the page records the arrival in a guest list and visual site plan. Its accompanying test used those five lines on 950 questions and reports a +0.1-point change with a 95% confidence interval spanning −0.6 to +0.9, described as not significant. The page says responses were retained and the test will be rerun monthly.
