AR application for my character(s)

Good morning everyone, I didnt really know where to post this thread. I think this forum was the best option for me.
So, to explain what I wanna do: I am still in profress of making a character, but its gonna be finished soon. I want to display that character in AR (augmented reality). I’ve seen some tutorials on youtube but realised I’d need to make an app for that.
Now, my question is: Is it even possible to transform that character into AR compatible mde where I could see rendered version on my phone? Also, I would really want to make it quite large so I could see the details.
Here’s the link to youtube video, to give you better idea what I’m talking about: https://youtu.be/plmDT7QyaKI
has anyone ever done something similar?
