At INDEX, a memory becomes perfume through a very human palette

The raw material is a story. Someone describes a place, a relationship or a remembered afternoon, and a conversational system asks what made it distinctive. At INDEX, that exchange ends in a physical fragrance. Between the words and the bottle sits a carefully bounded creative decision: which parts of a person’s account can usefully be expressed as scent?

Artist and technologist Tigris Li and perfumer Isabella Smith founded the project in 2025. As described in Dazed’s October interview, a conversation lasting around three to five minutes leads the system to select one to three of nine existing fragrance bases and blend them in chosen proportions. The bases are human-composed. The machine interprets and combines a palette; it is not inventing an unrestricted new chemistry for every visitor.[1]

The boundaries are part of the artwork

That structure gives the project a different creative logic from a model searching millions of possible formulas. A small palette can still produce varied compositions when selection and proportion change. More importantly, the perfumer has already made decisions about what each base can express and how the materials belong together. Personalisation operates inside those prior decisions.

Imagine two people mentioning rain. In one explicitly hypothetical story, rain means waiting alone after a difficult goodbye. In the other, it means the relief of arriving home while a storm begins. A keyword-to-ingredient lookup would treat the shared noun as the important fact. An interpretive conversation would instead ask about company, place, atmosphere and feeling. The creative question is not simply what rain smells like, but what work rain does in this particular memory.

The founders’ earlier Forbes interview frames the result as interpretation rather than literal replication. That is a useful promise to preserve. A bottle can offer an association with a remembered experience without reproducing the original room, recovering an objective record of childhood, or establishing what somebody must have felt.[2]

Li’s own practice joins technology to sensory installations. Smith told Dazed that she formulated every base and Li soldered the machine: human choices are present in the hardware as well as the fragrance. The conversational system connects a visitor’s words with that authored physical encounter.[3][1]

What the visitor contributes

A person is not merely selecting from a menu here. They decide what to disclose, which details matter, and whether the returned scent feels resonant. Those judgments cannot be settled by the fluency of the conversation. A beautifully phrased interpretation may produce a blend the visitor dislikes; a surprising blend may evoke something the dialogue never named.

There is also a difference between uniqueness and personal meaning. Even when two compositions share a base, or resemble each other closely, they may acquire different significance through the stories attached to them. Conversely, a mathematically unusual mixture is not automatically intimate or artistically successful.

Dazed reports the founders’ account that INDEX does not retain the complete conversation, while keeping a formula and summary. That is a stated practice, not an independent privacy audit. A visitor can therefore enjoy the exercise without assuming that a personal narrative becomes consequence-free simply because its output is a perfume.[1]

The most interesting version of the project leaves room for disagreement. The visitor can say that the scent fits, surprises them, or misses the point. In each case the system has made an interpretation available to the senses. A memory has not been extracted and bottled. Someone has found another medium in which to respond to it.
