Train custom vision AI on your iPhone — no code, no data science degree.
Collect a custom image dataset with your iPhone camera and train a vision classifier right on the phone, with no cloud round-trip and no code.
Every misclassification can be corrected in place, letting the model improve iteratively as you keep using it in the real world.
Assign HomeKit lights, outlets, fans, or scenes to specific categories so that recognizing an object in the camera view instantly brings up the matching controls.
Take your trained classifier beyond FieldDay and reuse it in Siri Shortcuts, Snap Lens Studio, Xcode, and other popular formats and tools.

Real-time vision AI models and a full platform to train, annotate, and deploy them
One model family covering detection, instance segmentation, pose estimation, oriented boxes, classification, and tracking, tuned for real-time inference on GPU, CPU, and edge devices.
Label data with SAM-assisted annotation, train on cloud GPUs with AutoTrain, and deploy to managed regions that scale to zero when idle.
Ship trained models to ONNX, TensorRT, CoreML, TFLite, and many other formats for cloud servers, mobile devices, and embedded hardware.
Adopt the open-source AGPL-3.0 release, or purchase an enterprise license to embed YOLO in closed-source products without copyleft obligations.
