Retail Computer Vision Kotlin Multiplatform On-device ML

Zorky: computer vision for finding orders in retail

A computer vision SDK and admin panel for the store associate's mobile app. The associate points the camera at a shelf and Zorky finds and highlights the right order or shoebox within seconds. Even offline.

Zorky — admin dashboard with metrics and the camera search module

Challenge

Pick-up point and store staff search for orders by eye, going through dozens of boxes and labels. It is slow, costly and leads to handover errors, and during sales search time grows faster than the load. Cloud recognition is not an option: connectivity in warehouses and back rooms is unreliable, and camera frames must not leave the perimeter.

Solution

We built Zorky — an on-device model that recognizes numeric codes on labels in the video stream and highlights matches right in the frame. The module plugs into the existing associate app via a single Kotlin Multiplatform SDK for Android and iOS, and a multi-tenant admin panel manages users, devices, ML models and quality metrics.

Smart in-frame search

Orders by last 4 digits, shoes by 3 article digits, whole sector with a “Found X of Y” counter

100% offline

The model runs on the device; frames never leave the phone — only anonymized metrics are sent

Kotlin Multiplatform SDK

One public API for Android 24+ and iOS 15+, CameraX and CVPixelBuffer adapters, private Maven

Admin panel

Users and roles, device fleet, model versions with A/B and rollback, analytics and reports
