Ye Kya Bak Rahe Ho |work| Now

It sounds like you're mixing Hindi slang with English. "Ye kya bak rahe ho?" roughly translates to "What nonsense are you spouting?" or "What are you rambling about?" in a casual/abrupt tone. Adding "— interesting feature" makes it feel like a humorous or sarcastic tech/product review — as if someone called a new app update nonsense but then admitted it's an interesting feature. So you're likely joking: "What are you blabbering about? Oh wait, that's actually an interesting feature."

If that was your intended meaning, clever wordplay. If you were genuinely asking what someone said, I can help translate or clarify. ye kya bak rahe ho
