Hey HN! I'm super excited to share Markup with you, which is a totally free & open-source annotation tool that helps you transform unstructured text (e.g. news articles) into structured data that you can use for building, training, or fine-tuning ML models!<p>Markup uses GPT-4 to learn as you annotate, and speed up the process by predicting complex entities and attributes!<p>Check it out: <a href="https://github.com/samueldobbie/markup">https://github.com/samueldobbie/markup</a>
