Real world use cases might be; Classifying the users mood from mouse movement, classifying the microphone audio. I.e. process real time data that might be too large to upload.
I personally haven't seen any NNs being used in browser apps, but there are plenty of existing mobile apps that has NNs to classify audio/video/etc directly on the device.
