What flashcards do well
When parents already have a clear word list, fixed cards can help children repeat and self-test quickly. They are simple, direct and easy to run.
Flashcards review words. Ray turns daily life into a vocabulary system.
The strength of flashcards is repetition. The strength of Ray is source: children first meet English in a real scene, then save and review it.
What Ray does well
Ray starts from daily life: menus, story books, packaging and transit prompts. AI organizes the vocabulary, parents review it, and children meet it again in daily practice. The words come from English the child actually saw.
They can work together
Ray does not need to replace every flashcard. A stronger family pattern is to collect real input with Ray, then repeat important vocabulary over time.
