Hands down, the best annotation tool on the market Looked through half a dozen of annotation tools. This one was the most intuitive, the fastest, the most flexible. Judge: spent 3 days looking through others, Got up to speed and annotated 100 images on a free plan within an hour and sent the json file with the results to our developers. They have features that speed up annotations.

Excellent annotation tool I tried the free desktop tool. It works really well! Pleasant, intuitive, fast, it can definitely serve for small to medium size projects, as advertised. The annotations are accurate, the .json format to save them is perfectly appropriate. I'll give it 5 stars when it is possible to annotate videos rather than just images. Great tool anyway! [EDIT September 2021] Video annotation is now available, it really is a perfect tool, 5 stars without doubt!

I think they are the fastest to date. In terms of speed, SuperAnnotate beats out most of the competitors in the space. I love their automatic segmentation tool.

Easy to use and great costumer help SA is easy to use, works intuititively and the support is amazing. Have been using it for nearly a year now and the platform keeps on improving. Can definitely recommend!

Extraordinary platform for labeling Fully satisfied with SuperAnnotate's platform. Obvious advantages over other platforms particularly moving very fast and smooth during annotation work. From where I come from, the network tends to be a problem with frequent dips that rendered other platforms in the space along with image labeling work very hard. SuperAnnotate is amazing in the sense that it caches both server-side and individual machine data which saves me a lot of time.
