Studying abroad in the spring gets cold quick. In the first weeks, every country we traveled to sat around 35F°. Walking around and admiring architecture was entertaining until the cold overwhelmed us. To escape into warmth while staying entertained, we retreat into Sephoras. At the Sephora in Prague, Baran wandered over to the perfumes while I swatched lip liners on my hand. Baran is picky when it comes to scent, so I went over with her and asked what makes a scent “good.” There’s different concentrations of elixirs… and some notes are better than others… but I still couldn’t grasp what makes a scent objectively great.
Since my nose can’t pick up on the best scent for me, I let AI pick. Cosmotecha Vienna is a perfume shop located in Vienna. It’s run by EveryHuman, a company that creates personalized perfumes based on customers’ results to a personality quiz. With Baran’s love of perfume, my love of personality quizzes and our shared CS 3600: Introduction to AI class, this was the perfect activity for us to escape the Austrian cold.

Cosmotecha is a small, narrow space in the heart of the city. On the right, a sleek machine fills small viles with different liquids as the conveyor belt moves. Grey stools line the wall, seating customers as they complete the quiz and watch the machine. EveryHuman’s founder Frederik Duerinck says the machine is AI-enabled and learns how to create new scents with different ingredients. It understands what scents work well together, but takes liberties in creating new fragrances.
The personality quiz starts with multiple choice questions: words to describe your personal style, where you grew up (suburbs, city, countryside) and your hobbies. Then, there are questions similar to personality tests like MBTI. From not at all to very much, customers declare how much they relate with statements like, “is shy,” “easily distracted” and “is curious.” The quiz asked where we would rather be at that moment. The beach? The countryside? Baran and I chose the center of a bustling city. We didn’t want to be anywhere else.

Baran and I took our time answering each question. We added insight to make sure we both had a mix of our own personal vision and the perceptions from those around us. I usually think of myself as a dark, deep purple, but I’m more lavender than I thought. Baran is much friendlier than she thinks. The quiz ends by asking what scents we would enjoy in our fragrances. I chose to have more oud and musk and less citrus and fruit, but the machine had a different formula in mind.

Soon, three perfumes were created, boxed and handed to me. Spraying them on strips of paper, I was schocked. Each one was exactly how I wanted to smell. They weren’t just “fine” or “good,” they were right.
“636” is complex and grounding, reminding me of the luck I have; “audrey” is elegant and admirable; and “vitality” is youthful without smelling immature. While there was some intuitive reasoning behind the names for my scents, the main reason for their names was the reminders I needed.
I cycle through each perfume now, reminded not just of their meanings but of the experience of exploring a friend’s passion.
