I see no declaration that this is a machine generated site, but the aesthetic is a dead giveaway. The language on the “how it works” page is unmistakably LLM output. As a total novice in engines this site had the potential to educate me, but did the author vet the data at all? If the author doesn’t bother telling me they checked any output on this, what assurance do I have anything is accurate on the site at all? If I knew an actual engineer put their focus on this tool I’d feel much better about trying to learn something from it. Short of that it’s just a pretty (but predictable) interface.
The aesthetic is what I get any time I ask for something UI-like in Claude. But gosh darn it I like the look.
I'm a mechanical engineer who has written similar tools for work and hobbies. Producing pretty pictures does not mean that the model is physically accurate. Unfortunately, such tools seem be evaluated much more on flashiness and not on more reliable and objective criteria like physical accuracy based on verification and validation test suites. I'm seeing that in the comments here. I don't think LLMs make what I do irrelevant, but I have thought that I'm going to have to improve how flashy my simulations look to compete better with non-experts who use LLMs.
