Prodigy is a downloadable annotation tool and Python library for building, training, and evaluating custom AI systems. Created by the makers of spaCy, it supports teams working in natural language processing, machine learning, and computer vision, and can also be used with other libraries and tools. Its workflows cover information extraction, named entity recognition, text classification, image detection and segmentation, audio and video annotation, prompt development, and model evaluation.

The product combines a web application for fast, intuitive annotation with command-line tools and customizable Python workflows. Users can create their own data feeds, interfaces, and annotation recipes, while using model assistance and automation to reduce repetitive work. Prodigy is designed for developers and teams who want to build and manage their own training data and models.

The software runs on the user’s machines, with data kept under their control; it can also operate without an internet connection. Prodigy is offered under a lifetime license, with options for individuals and teams.
