Description
Developer tools for AI and natural language processing. Creators of spaCy and Prodigy.Ellf
Project Links
Description
Ellf integrates with AI-assisted coding tools such as Claude Code and supports end-to-end NLP development, including project planning, data preparation, annotation, machine learning, rule-based pattern generation, model training, analysis, quality assurance, and evaluation. It uses spaCy, Prodigy, and the Python ecosystem, and runs through a data-private cluster hosted locally or in the user's cloud infrastructure so data, models, and custom code remain under the user's control.Category: Developer Tooling
Prodigy
Project Links
Description
Prodigy is an extensible Python package and web application for efficient data annotation, model-assisted labeling, training, and evaluation. It supports information extraction, language model training, computer vision, audio and video annotation, prompt engineering, and custom workflows. Prodigy runs locally or on user-controlled infrastructure, keeping data and models private, and integrates with spaCy, Hugging Face, LLM providers, PyTorch, TensorFlow, and other Python tools.Category: Developer Tooling
SpaCy
