Prodigy

Prodigy is a scriptable annotation tool by Explosion AI designed to create high-quality training data for NLP and computer vision models as efficiently as possible using active learning to prioritize the most informative examples for human review. Its stream-based annotation workflow and keyboard-optimized interface minimize annotator effort while maximizing the information value of each labeled example, reducing the volume of training data needed to reach target model accuracy. NLP teams building custom models for named entity recognition, text classification, relation extraction, and image annotation use Prodigy to create training datasets faster and more cost-effectively than traditional annotation platforms.
