The tooling is very intuitive and enables very accurate pixel-level annotations. Especially once you develop an approach and rhythm for how to annotate a specific project, you can move very quickly and accurately. I particularly like the paintbrush tool and some of the "behind the scenes" functionality that enables you to move through repetitive, overlapping regions quickly. They are always making improvements to further improve the workflow, tooling, and overall process so if something doesn't exist today, it might very shortly. Their support team is also very helpful when we run into issues. The ability to upload from a local source or s3 is very helpful. There's a lot of cool functionality which we haven't had the need to use (for video and pose labeling, for example), but it looks really efficient.

For our company, which specializes in ML solutions, we have tried several popular tools for image annotation/labeling, and SuperAnnotate had the easiest to use and the most relevant toolset for us. Particularly their smart semantic image segmentation tool is gold! It speeds up the process a lot. It's been more than a year we are using their services and we are very satisfied with it.

Very quick adoption time for our annotators who do not always come from a technical background. Furthermore, the UX of the platform has thus far been excellent, bridging speed and versitility (desktop version of SuperAnnotate) with nigh-instantaneous customer support. We have tested this out against alternatives and SuperAnnotate is by far the best we had.
