I'm not really familiar with Rubber ducky and just quickly searched the web. So it is a tool to create tests? Or what is it exactly? Is it an Ai tool? Can it read the entire code or documentation base and then pretend to be a student or developer that asks you questions about it?
I am not down playing the other issues it has, like licensing, cost, environmental impact, dependency and privacy issues. These are still an issue with such an online LLM tool. But that is not the point of my post and does not take away about a "good" use case. In my opinion.
