Pros & Cons from Real Users Pros The team was really involved in helping us work and interact with the platform. Feedback for data labelling was very good. The platform has a good free tier, for many small projects you may not even need to upgrade to the higher tiers. It’s solid, we use it from the cloud and we had no problems importing all of our assets from S3. Our project is in the customer satisfaction sector and Ango Hub provides relations between audio and text annotations, as far as I know I didn’t see other platforms with this functionality. - Platform supports text, PDF, image, audio, and video - Support responds very quickly - Having an API is a neat addition - It has some more obscure labeling types like rotated bounding boxes which we actually ended up needing - AI labeling assistance options - Generous free trial Cons There was no aspect we did not like. It was a great experience. There are AI assistance options such as automated recognition of objects and polygons, but all of them are for images. If you are labeling text or audio, sadly there is no AI assistance. Importing files from cloud storage was smooth but it required us to make our own JSON file. That is a one-time process though. - Importing data from cloud storage is not an instant process - Doesn’t look too great on mobile
