I'm guessing since the website says "We have developed proprietary Machine Learning algorithms" they won't really share any fun technical details :(

Yeah, seems alright in order to bootstrap something. Like many of these new AI/ML workflows, I don't think they'll replace any professionals, as the results are still lacking without human intervention, but I think many (including this) is a huge time-saver for professionals who can use it as a starting point and then modify it from there, rather than doing everything from scratch.
