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.

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!

Extremely helpful and convenient Extremely helpful and convenient was looking for a tool to annotate documents for my master-thesis - found this via open-cv. good examples, easy to learn, and covers all my use-cases (separate folders for separate documents for instance). the webservice is top-notch, uploads work fast, and the entire project can be stored in one place and accessed from anywhere. Since i reached the limit for the free version, i reached out to the team, which got back to me instantly and gave me an appointment on the following day. the staff is very friendly, understanding and supportive! now i can conduct my research exactly the way i need - big thanks and a clear recommendation for anyone with a use case :)
