umami.

The biological taste locus engine. Decode your receptor-level savoriness sensitivity, create your sensory business card, and match food-serving restaurants on a local map.

New to the engine? Select a tier below to build your taste locus first.

Quick Palate (Basic) 6-AXIS

Fast 6-dimension screening for casual diner matching. Generates an instant local locus without an account.

Member Locus (Enhanced) 20-METRIC • 5X

20 physiological markers across receptor genetics and lipid coating. Includes interactive visual restaurant map and QR card.

Biological Typing

Maps receptor thresholds (TAS1R1/TAS1R3) and 5'-ribonucleotide synergy factors rather than subjective food names.

Scannable Cards

Export personal palate business cards with dynamic theme selection and camera-scannable QR tokens.

Food-Serving Venues Only

Excludes coffee houses and beverage stalls, focusing strictly on actual restaurants, gastropubs, and dining kitchens.

Science & FAQ

Biological gustatory fingerprinting and venue matching

What does "Taste Locus" mean?

Locus comes from the Latin word for "place" or "location." On this site and on your sensory business card, it carries two connected meanings:

The Mathematical Meaning: In data science, a locus is a precise coordinate in multi-dimensional space. Your taste locus is the exact intersection of your sensitivity scores across glutamate affinity, nucleotide synergy, chemesthesis, sodium substitution, and lipid finish.
The Genetic Meaning: In biology, a locus is the physical chromosomal address of a gene. Savoriness reception is heavily governed by variants in the human TAS1R1 and TAS1R3 receptor genes. Your locus token serves as your palate's digital gene marker.

How does the algorithm turn my answers into a DNA fingerprint?

Each sensory response is calculated into normalized values between 0.0 and 1.0 using high-resolution psychophysical curves, salted deterministically by account signature, quantized into 8-bit hex registers, and assembled into an immutable locus byte string.

What is the difference between Basic and Enhanced Member accounts?

Basic (6-Axis): A rapid 60-second questionnaire for guest diners. It calculates your foundational savory threshold, ribonucleotide preference, and bitterness response without requiring an account.

Enhanced Member (20-Metric • 5x Resolution): A deep calibration across 5 specialized biological modules. It unlocks your downloadable 300 DPI sensory business card, persistent browser vault, and visual dark-mode restaurant map.

How does the business card and friend comparison work?

When you create an account, the site generates a 300 DPI sensory card featuring your taste locus and a live QR code. When a friend scans your card with their phone:

If they don't have an account, they can view your profile and are invited to take the test.
If they have a profile, the algorithm calculates a Compromise Centroid with penalty bounds for acid and fat sensitivities, predicting group dining happiness without veto stalemates.

Why are coffee shops excluded?

Umami and biological flavor matching require actual culinary preparations (proteins, broths, gravies, reductions, and fermented sauces). The spatial query strictly filters for actual restaurants, gastropubs, and dining kitchens, purging coffee houses, juice bars, and pastry shops.
