Video and image annotation tools built for scale

The KeyLabs image and video annotation tool was built by annotation specialists to give you more control and visibility over your projects.

High performance features for teams that move fast


Segmentation lets you annotate complex images by separating different elements into multiple segments (or image objects) using unique colors and attributes. This makes it easy for annotators to create and review sophisticated data sets.

Image/Video Classification

Classification puts you in direct control of how you label images and videos. You can apply a single label or multiple labels, identify image similarities, and auto-switch between multiple images to increase labeling speed.

Shape Interpolation

Shape interpolation uses classless object tracking to improve the speed and efficiency of your annotators. Simply define a start and end point and Keylabs will use object localization across multiple frames.

Automatic Annotation

Annotate at scale with automatic annotations that work with any object. Let the Keylabs neural network annotate high and low-res images with no training required, so you can improve the speed and accuracy of your training data.
