The Universal Data Tool (UDT) is an open-source web or downloadable tool for labeling data for usage in machine learning or data processing systems.

The Universal Data Tool supports Computer Vision, Natural Language Processing (including Named Entity Recognition and Audio Transcription) workflows.

The UDT uses an open-source data format (.udt.json / .udt.csv) that can be easily read by programs as a ground-truth dataset for machine learning algorithms.

Labellerr is an automated data labeling platform to help ML teams to build training data for their computer vision and NLP model training. It also provide expert/human in the loop services to its customers for high quality labeling.
