Context: LaTeX is a typesetting system. When compiling a document, a lot of really in-depth debugging information is printed, which can be borderline incomprehensible to anyone but LaTeX experts. It can also be a visual hindrance when looking for important information like errors.
I use overleaf.
Well, overleaf.com is for LaTeX, but typst.app is for Typst, a superior alternative witch is in beta. So for some people it won't be enough (yet), but for me it's awesome.
How is Typst "superior" to Latex?
Since for me it has all the needed features, for me — it's by far superior (even compared to LuaLaTeX which is the last thing I used). But some people, mainly from academia, are still can't switch due to some features missing. A few people were able to create thesis in Typst (including myself). In the long run it will be 100% superior. In the mean time, there are a few hacks to enable some features that are otherwise not implemented yet.
