The best thing about this tool is that it offers both free as well as paid plans, which makes it very easy for users to choose their preferred plan. It also has an excellent UI/UX design, which helps in making your work much easier. I am not able to find anything negative or dislikeable in this software so far. This seems like one of the finest data labelling tools available out there right now. If you are looking for a good product with great features then definitely give this tool a try! We use this tool for data labeling from our images files. With its help we can easily label all types of file formats such as JPG, PNG, PDF etc. There won't be any issue when working with multiple documents at once using this program. Moreover, it's ease of access and user-friendly interface really make us enjoy while using it.
