Image Annotation API

Best-in-class object recognition to power the next generation of computer vision via API.

Use Cases

Our combination of humans and machine learning is built to solve a wide range of use cases. Our goal is to power innovation, wherever that may be.

Pixel Perfection

We focus on quality so you don't have to. Through world-class tooling and a robust quality assurance process, we provide the highest accuracy in the industry.

We understand the need for quality. The prerequisite for an amazing algorithm is immaculate training data. That's where we come in.

We've built advanced tools that allows our Scalers to produce pixel perfect results in minutes. Each request passes multiple trained Scalers for review to ensure we only deliver the best.

Line, Polygon, and Cuboid annotation are in BETA. Contact us for access.
