I find it irritating that even after reading their front-page and the "How you can use WT" I still have no clue what it is supposed to be. Is this an embedded browser? Is it a C++ app GUI that allows you to use HTML like construction? Is it an emscripten application? How can it work without JS enabled? Is it compiled into pure WebASM? What the heck do they mean by connection? What connection? What does have PDF and DB to do with all that? Etc.

Very poor marketing imo. After reading all this I have even less clue what it is supposed to do.
