“이/가” is the Korean version of this. It depends on the sound of the word that precedes.

I still remember seeing it when I first started using Windows 95. As a kid, I was amused that it didn’t know which one to use. Really, I didn’t even know that I was making that choice (and couldn’t say what the rule was).

If anyone is interested about it, this page explains https://www.90daykorean.com/i-ga-grammar/
