Here's the chain so far: we asked six made-up "persona" readers — stand-ins for different kinds of learners, like a 12-year-old (KID), a busy executive (EXEC), or a parent helping with homework (PARENT) — what they'd want from each flashcard type. We built a visual gallery of mockups from that. Then we had those same personas grade the gallery: 26 things they loved, 2 they liked, 1 they merely tolerated, 4 they said were missing. We then fixed the 4 misses (bigger tap targets, icon-based register tags, a new KID vocabulary card, a reused "where am I" progress bar). Now it's your call — do we build the real thing to match this gallery, and how do we resolve a few specific trade-offs inside it?
