If your goal is to be simpler, and also more powerful, could you write down what that means?

If your goal is to just poke around without a plan, or to just copy features without a unifying vision, it seems unlikely it ends up simpler or more powerful than anki.

As far as I can tell, there's no vision written down anywhere, no list of things other systems got wrong but you'll get right, no insight into what needs to be done in this space.

The only selling points / differentiators I see listed right now are: "no paywall/free, open source". Those do not differentiate it from anki.
