reminds me of http://www.thai-language.com/ (it's safe). it was around long before Google Translate got good enough. i don't know the authors/maintainers, but afaik, everything is entered manually. this is the "analytical" approach to language. most translations before Google Translate went full ML used an analytical approach.
anyway, long story short, turns out "analyzing" a language to "understand" it GREATLY underperforms probabilistic/statistical methods like ML.
also reminds me of trying to label parts of speech in Vietnamese. there's a school of thought that finds it useful...then there's another school of thought that plainly points out words that can be verbs, nouns, adjectives all in different contexts.
