AI annotation tool for NLP
Prodigy provides an interactive annotation interface that lets users label text data for NLP tasks in real time. It supports text classification, named entity recognition, and sentiment analysis out of the box. The tool embeds an active learning loop that suggests the most informative examples to label next. Built on spaCy, it can import existing models and immediately apply predictions during annotation. Target users include data scientists, NLP engineers, and academic researchers who need high‑quality training sets. Pricing is a paid subscription only, with no free tier. The web‑based UI runs locally and offers keyboard shortcuts for rapid tagging, reducing mouse dependence. Custom recipes written in Python let teams define bespoke workflows, integrate external APIs, or modify the annotation logic. Prodigy exports labeled data to JSONL, CSV, or spaCy‑compatible formats, simplifying downstream training pipelines. Collaborative projects can share a server instance, allowing multiple annotators to work simultaneously while preserving version history. Model‑in‑the‑loop feedback updates predictions as the underlying model improves. Annotation projects can be versioned and rolled back, ensuring data integrity and audit logs. Compared with open‑source alternatives like doccano, Prodigy emphasizes speed and model‑driven selection rather than pure manual labeling. It excels when rapid iteration between model training and data labeling is required, such as building intent classifiers for chatbots or entity extractors for information retrieval. The subscription includes regular updates and priority support, making it a reliable choice for commercial teams that value consistent performance over a free solution.
