Easy tool for Data Annotation.

What do you like best about CVAT.ai?

The best Cvat.ai does is that it has many annotation options that works with different Computer vision algorithms. Boxed, polygon and even Segmentation annotations are possible. They have few Pretrained models to select and annotated based on them, or we could upload our custom pre trained computer vision model and annotation based on the already annotated dataset. Very helpful tool if you want work on custom models as well.

What do you dislike about CVAT.ai?

Intially it can be little time consuming to figure out, how you uoload the data and start annotation. Not beginner friendly.

What problems is CVAT.ai solving and how is that benefiting you?

I use CVAT for annotating image data for my use case. I have used them seperately and downloaded the annotation format for the images, as well imported a custom trained model and added more data to continue annotation as per my Custom model required label structure. Finding annotation for polygons especially the shape of the polygon for my use case was intricate and Cvat helped me in it. I can't be disclosing more information about how i use them or for what project due to the NDA. If this review is not good enough stop sending me emails to review products.
