Vocabulex

Vocabulex is another entry into the crowded AI-flashcard space, and I'm skeptical until someone shows me why their "adapts to your memory" claim is different from the dozen other apps saying the exact same thing about spaced repetition. I don't have access to the actual product, so I can't speak to whether the AI personalization is genuinely better or just a smart-sounding wrapper around a proven mechanism — but that tagline needs serious backing if they want to stand out in a market where Quizlet already has 50 million users.
