I like how it is so easy to learn and implement for literally anything.

A large number of high-quality images that can be used to create a dataset for training neural networks

Roboflow is a fantastic user-friendly platform that I have used extensively over the past year, mainly to annotate images that are subsequently used to train AI models. Roboflow allows one to annotated images from scratch. The annotated images can then be used in several ways.  First, they can be downloaded to a local computer and be combined with other (annotated) images in future projects.  This prevents the need to annotate a second time and one can choose to use the same train:valid:test distribution as was used in previous projects. Second, the annotated images can be used to develop a version of the project that can be used to train an AI model. Roboflow offers the possibility of preprocessing and augmenting the initial images to create a larger library of images that have a variety of rotation, brightness, hue, etc. Third, the annotated images can be used – via the project version – to train a model directly on the Roboflow platform. Alternatively, Roboflow supports the possibility to download the annotated images (including the preprocessed and augmented images) to another platform where the AI model can be trained.
