Where’s can I check my Japanese writing?

I started studying japanese a month ago, now I'm starting to connect words and making full phrases, but I don't know if I'm doing it right, and I don't wanna fill my teacher's dm with questions like "is 'nani ga suki?' right? Or I have to put the 'ka'?", or "how do I say this ultra specific word that u probably didn't ever used in ur life in Japanese?" Or even "how do I use this new word in a sentence in this especific context?". So I need and app/site that can just help me check if the writing is correct, or if I can improve it in a way or another.

I was using Google translate only, but it is kinda lame, when I write phrases like "I prefer dogs than cats", it shows words that I don't know yet, when I was just trying to learn the 'yori mo', cause of that song "ruby chan, nani ga suki? Chocominta, yori mo a-na-ta!"

Well, idk if it exists, or if is just better I just use some ai like Gemini or gpt, but I was hoping someone would know
