Nope, not an ak clone, as far as I know. I'm actually not so sophisticated on identifying what cart a cart is derived from, but I'm certain it's not an ak clone (if it were an ak clone, It'd probably have akaio support to some extent, but r4i gold 3ds only has wood r4 support). You'd have to open the cart up and compare the pcb/build to that of another.
EDIT: if you're saying that the UI looks very similar, that's because both are created from the same source code.
Anyways, r4i gold 3ds would be recommended, since some acekard 2i's suffer from contact issue. Fortunately, my ak2i haven't had any contact issues, though.
