Labelbox vs Scale AI

Labelbox offers labeling software and also supplies expert data through Alignerr, a network of over 2.6 million vetted experts. Scale AI delivers ready-made labeled data produced with its own software paired with online workers who join through its job websites. If your own people will do the labeling, Labelbox is the fit; if you would rather receive finished labels, a service like Scale AI is.
