Mochi – Spaced Repetition with Modern UI (opens in new tab)

Unlike Anki, I believe Mochi is proprietary.

Love the UI. Do consider adding product walkthrough for guest account. I couldn't make much sense of the purpose of the product or navigation. May be anki users will get it better though.

btw, are you using antd? or any specific ui library?
