I have an Anki deck of kanji that I copy-paste from Jisho.
As Vanilla here mentioned, it’s probably not super necessary. At this point, I just find it stimulating more than anything else. Studying kanji did help with the 150-ish jо̄yо̄ kanji that WaniKani doesn’t have, but now I’m adding jinmeiyо̄ kanji, which I almost never see in the wild.
Since I hit level 60, I’ve been trying to put more of my Japanese study into immersion. I try to center my practice around reading/listening without English. I sometimes go weeks without adding new items, though. Guessing from context is good practice too.
EDIT: If you’re interested, here’s a thread about my deck. I just updated the link, so the deck has 460 kanji now.
