I have tried this tool for JS/TS. I really like the UI,I want to like this product more, and I continue to to try to use it, with the hope that with more training, it will become truly useful and a net time saver.
My first install did not work out of the box, and was met with semi ambiguous errors, but I eventually figured it out. My current use of it sometimes (I think) saves a little time by generating boilerplate, but I have to refactor it every time, or scrap it all together and just use the skeleton. It seems like there is some setup that can be done to configure a bit more, but at the time I looked into it, this information wasn't readily available or intuitive, and it's hard to find free time to dedicate to setting up a work tool.
That being said, I have high hopes, and will continue to poke at it :-)
