Labelbox vs Scale AI
Scale AI ships ready-made labeled data, made with its own software and online workers who sign up through its job websites. Labelbox instead offers labeling software, and it also supplies expert data via Alignerr, a network of more than 2.6 million vetted experts. Choose Labelbox when your own people will do the labeling; pick a service like Scale AI when you would rather receive finished labels.
