Cadryl: annotate images

Turn your images into a dataset on your Android device.

Import images in batches. Add and edit boxes, points and masks. You decide which annotations to approve. Your projects and corrections are saved locally.

A compatible model can suggest annotations when you import a batch. Review and correct its results before approving your images.

Export your dataset in the available formats, including COCO and YOLO where supported by your annotations. Publishing to Hugging Face is optional and requires your confirmation.

With a model that supports local training, prepare a training run and follow metrics suited to its task. Training compatibility depends on the model you choose.
