“Versatile, elegant and ever evolving annotation tool that never disappoints”

The fact that I can use polygonal or freehand tools, easy to use sculpture tool and the way I can easily communicate with the reviewer. Simple but powerful interface of the Encord tool is a lifesaver especially when I am working with annotation intense studies with multiple objects...

“Easy to use training data platform for annotation and model validation”

The option of serving our models on their platform gives us the flexibility to use it as a ‘model proof-of-concept / validation system’ with a human in the loop that helps to uncover blindspots and edge cases in our production models. The annotation tools are easy to use and cover most of the various annotation types we need.
