The language of perfumery
A note is not necessarily an ingredient. It is an image the nose recognizes.
A formula may contain no cherry, leather, or wet earth. Yet a combination of materials can create an impression the nose recognizes in exactly those terms.
One person may smell almond, another a cherry pit, and a third a warm liqueur. The names differ, but they may describe the same facet of the composition.
Declared notesThe brand’s intent
The official note list from the fragrance description: how the composition was conceived and presented.
Perceived notesWhat people actually smell
Notes that repeat across real reviews of wearing the fragrance: what comes forward, stays on skin, and is remembered by others. They can be more prominent than the declared list suggests.
○The declared list is not shown on this card. Perceived notes work on their own: they show what comes forward on skin, holds, and stays in the trail.
Intent and result
The lists may not match. That’s normal.
The brand describes the formula. On skin, dose, warmth, and time strengthen some notes and hide others.
That is why people may smell cherry, metal, or a “clean shirt” even when those notes are not in the declared list. Both lists are true: one is about the intent, the other about the result.
Declared notes say how the fragrance was intended. Perceived notes show what people actually smell.
Accords
Several notes. One complete impression.
As in music, an accord comes from a combination. Woods, spices, and smoke can create the impression of leather; florals, musk, and aldehydes can suggest a clean shirt.
Notes show individual details. Accords show the overall texture, mood, and direction of the fragrance.
Recurring signals
One review is an opinion. A recurring impression is a signal.
People may use different words for the same facet. What matters is not one phrase, but the images and sensations that recur across perceptions of the fragrance.
Tell Index’s perfumery algorithm identifies these recurring signals and separates a stable characteristic of the fragrance from a chance impression.

Before you buy
Choose more than a composition. Choose an impression.
A fragrance shapes first impressions, fills space, and stays on clothing. A note list alone is not enough.
Tell Index helps explain the practical effect: what people may smell, which image they may read, and how well the fragrance fits you.
Our core innovation
Tell Index is the key number of a fragrance.
Tell Index is both the name of this portal and our unique metric. Every fragrance gets its own index from 0 to 100 — a clear point of reference for navigating and comparing fragrances.
Tell Index measures signal strength: how distinct an impression a fragrance creates and how clearly it speaks about a person before an introduction. It is not a quality score or a popularity rating.
General Tell Index shows the fragrance’s overall signal strength. Personal Tell Index shows how that index may change for you based on style, dose, city, and life situations.
