Real-time object detection → emoji overlay, 100% on-device
Point your camera at anything and watch matching Apple emojis appear instantly.
Powered by YOLO26 and CoreML on the Apple Neural Engine.
Pet detection | Room scan | Kitchen | Workspace | Debug mode

All ML inference runs on a dedicated DispatchQueue at .userInteractive QoS. Results publish back to the main actor via Combine for SwiftUI rendering.
VisionEmoji does not collect any data. All processing runs entirely on-device.
