Awesome data annotation
A list of tools for annotating data, managing annotations, etc.
Contributing: I gladly accept additions to the lists below; please submit an issue or pull request with any updates.
Just looking for a recommendation of the one best open source annotation tool? Me and several other people in industry and academia have independently found CVAT to be the best choice for Computer Vision tasks.
