Markup

Building an NLP or ML dataset by hand is one of the most tedious parts of any machine learning project, and the annotation work only gets worse as the documents pile up. Markup is an open-source annotation tool that transforms unstructured documents into structured formats for NLP and ML tasks like named-entity recognition, taking the worst of that work off your plate.

What makes it genuinely smarter is that Markup learns as you annotate, predicting and suggesting complex annotations so the process gets faster the more you use it. It helps turn free text into structured datasets rapidly, and it is powered by GPT-4 under the hood, giving you both the speed of AI and the precision of human oversight in one workflow.
