I use Anki. It's poorly-designed, but it's the best thing that I've used so far. I'd love to have an upgrade, but you have to convince me that your tool is actually materially better than Anki, and doesn't just "look beautiful". Using language like "modern" is a turn-off - it evokes feelings of Electron implementations, webtech, slow interfaces, and web design that wastes tons of visual space to be "minimal".

I see that you wrote a page that ostensibly compares it to Anki[1], but it doesn't tell me anything. You say that it's easy to use, but does it also support all of the features that Anki has? You say that "you won't have to worry about settings or addons", but settings are there for a reason (because people have different needs), and does your tool subsume all of the functionality of all of the Anki addons that people made? You say that "we release new features every week", but where's the list of features that have been recently added, and how does the feature-set compare with Anki?

I want a better tool than Anki, but you have to show me that it's actually better. Otherwise, you're not going to win over either the Anki users or the Quizlet users.
