Nim: Language Cards

Meet Nim, your clever fox study buddy. Smart spaced repetition flashcards with AI-powered card capture.

Learning a language? Nim turns vocabulary into flashcards you'll actually stick with.

Nim is named after the little fox who sits with you while you study — he knows your cards, cheers you on, and keeps the streak going. Every session you've got company, so progress feels like momentum instead of homework.

Under the hood, Nim uses proven spaced repetition scheduling: cards you know well show up less, cards you're shaky on come back sooner. Rate each card Again, Hard, Good, or Easy, and your next review adjusts automatically.

Built for language learners:

Multiple decks side by side (Chinese, Korean, English, and beyond) Pinyin and romaji shown right on the card front Grammar notes and usage context, not just bare translations Audio pronunciation and one-tap dictionary lookup Customizable daily limits and new-card pace, so you learn at your speed

Go Pro for unlimited AI-powered card capture — snap a photo of text and let AI turn it into ready-to-study flashcards, across every supported model. Try it free for 7 days.

Whether you're cramming for a trip or building fluency one card at a time, Nim makes the habit easy to keep.
