We've taught your smartphone to tell whether fish is truly fresh
A visual recognition model trained on thousands of images of fish species, calibrated against the visual indicators used in freshness assessment schemes. It analyzes multiple signals in the same photo, in real time.
In the app, tapping a badge opens the full assessment of the fish's freshness.
How it works
Behind Selya is an artificial intelligence model that analyzes images using established data and parameters, providing a consistent and transparent assessment. Each photo is analyzed in real time against multiple indicators simultaneously.
Assess visual signs of freshness with Selya
These are the signs that reveal the quality of fish, and industry professionals know them well. Selya uses AI to make this information more accessible to consumers too.
Clear eyes with depth
Convex and bright, with a black, clearly defined pupil. As freshness declines, they become cloudy and sunken and lose definition.
Moist, shiny skin
Taut, firmly attached, and vibrant in color. Selya analyzes texture and variations across the entire visible area, detecting any unusual surface films.
Bright sheen
This is the parameter closest to instinct, but made measurable. Selya assesses the fish's overall sheen: the type of reflection, its uniformity, and its intensity.
Vibrant color
Vivid and uniform in fresh fish, dull and altered in older fish. Selya assesses color variations across the fish's entire visible surface.
The result, in a word
The result isn't a complicated report. It's a clear, immediate indication that anyone can understand.
Very fresh — Buy it without hesitation
Recently caught. Take it home and cook it however you like.
Fresh — Excellent product
Good product. Cook it by tomorrow.
Cook it today — Consider your purchase carefully
Still good, but cook it today.
Better to choose something else — Consider carefully before buying
The signs of freshness are weak. Ask the fishmonger or choose another fish.
Transparency note
Selya is a tool that supports informed choices and promotes quality throughout the fish supply chain. It does not replace the opinion of regulatory authorities or the assessment of industry professionals and, like any AI system, it can make mistakes.
Species identification
Selya automatically identifies the species of the fish in the photo by comparing its shape, color, proportions, and morphological features against an extensive reference database, providing quick and reliable identification directly from your smartphone.
