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.

Superannote I have had the opportunity to work on the platform for 4 months and have seen first-hand how intently they respond to our feedback and provide updates that boost efficiency even further. Few features in SuperAnnotate are just a lifesaver for annotators. It provides a great deal of editing capability on existing annotated images. This has been crucial in some of the work we have performed using this platform. Also with great ease of use coming from features like auto-segmentation and the superb project-based analytics generated to keep the management side organized, it’s almost impossible not to recommend SuperAnnotate. I have found this one of the only platforms to use Neural Network training, Quality Control, and AI-Augmentation. I hope to explore more of these features further for research purposes and project requirements.

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!

Great team, great product, great support We needed an experienced team with great software to help us develop a new pose detection algorithm. We needed to find the right model for our project which required experimentation and iteration with the annotation team. The Superannotate team has the right team at the right price. Their software, customer support and annotators did a great job of executing on our model.

5* - Great efficient tool with good UX and an extremely helpful Customer service team. Our main consideration for a tool was something that could handle an extremely large data set with around a million to 2 million images. We have shortlisted a lot of tools but we ended up choosing super-annotate as it had an user friendly UX and very high rate of annotation. The way we have handled a team of 40-50 annotators was very easy and hassle free.
