Image annotation tool

Precision image annotation for real-world AI systems

Label millions of images with AI pre-labeling, custom model integration, and post-processing that keeps edges clean and accuracy high.

Image annotation capabilities

ML assisted

Auto-detects object boundaries: pick a tool and the AI generates the contour.

Magic wand

Segments complex objects in one click, instantly building a mask around them.

3D tool

Works in 3D space with cuboids and point clouds.

Edge smooth & Healer

Exclusive post-processing that smooths edges and auto-corrects minor inaccuracies.

Multilayer annotation

Separate layers let overlapping objects be annotated without interference.

A-Z order

Layer ordering tells the model which objects sit in front and which are occluded.

Object linking

Establishes logical connections between separate annotations.

Hierarchical attributes

Structures frame and object metadata through dependent attributes.
