What is Prodigy?
Prodigy is a downloadable developer tool for creating training and evaluation data for machine learning models, delivered as a Python package that includes a web application. You can define a label scheme using real examples, annotate with the help of a model, and then train and evaluate a model on the results. It runs only on your own computer and does not send data to external servers, and the models you create are yours. Python functions let you customize the data flow and annotation interface as you like.
