Anki is the opposite of edutainment brain candy. It's a serious, no-frills tool that does one thing exceptionally well: help you remember stuff forever using spaced repetition.

The research backs it up—this method works. Medical students use it to memorize thousands of drug names and disease pathways. Language learners swear by it. It's free, open-source, and has zero dark patterns.

But here's the thing: it's boring. Deliberately so. There's no XP, no avatars, no rewards. Just you, your flashcards, and the algorithm deciding when to show them. For self-motivated kids (usually 12+) who want to ace Spanish or memorize world capitals, it's gold. For younger kids or those who need external motivation, it'll feel like homework.

The content safety caveat is real—Anki doesn't curate decks, so you need to preview anything your kid downloads. But the app itself? It's about as safe and enriching as educational software gets. Just don't force it. The moment it becomes a chore, the learning benefits evaporate.
