The trademark infringement claims are serious. Metal is more than just 3d graphics framework. It is a general purpose parallel computing framework, and this application would very much fall within the purview of its trademark. E.g. if you were going to implement an embedding based classifier on iOS/MacOS you would most likely use compute shaders written in Metal. The fact that the website styles are almost identical down the color palette doesn't help the case: https://www.getmetal.io https://www.getmetal.io https://developer.apple.com/metal/ https://developer.apple.com/metal/
