The system is very easy to use, it has good visualizations of your labels and their scores which makes understanding the label model really straightforward. It also lets you train models in multiple languages at once. I dislike that there are not many ways to visualize what each label means so sometimes finding out why an existing label was given can be difficult. Try it if you want a tool that's simple to setup but powerful enough for most needs! We're solving our labeling problems with this product by creating accurate machine learning datasets.
