Can you vibecode this?

Yes

SRS flashcard decks, AI writing feedback, and spaced-repetition recall flows are all standard buildable features. The React/Node stack is already in place. A weekly live Google Meet session is the only human element, and customers aren't paying for it.

Why people pay Language Babe Trainer
