Darwin is a great tool for annotating. We found it very easy to manage images, annotations, and annotators. The images we use in our line of work should stress-test most image-processing services, but Darwin seems to operate fast enough for our satisfaction. There are some niche tools we use that are missing in the interface, but their support team is very responsive, I felt our feature requests are heard and being worked on.

The interface is easy to navigate and intuitive. Support is prompt and knowledgable. The auto-annotate tool is world-class and saves substantial time for semantic pixel labeling.

Multiple options to select from when exporting annotations s3 integration was just perfect for me as i was able to break the video down into frames automatically right after after upload.
