KaChiKa - AI Photo Flashcards0.9.10 - App Store

Turn any photo into a language lesson.

KaChiKa uses AI to instantly identify objects in your photos and generate vocabulary cards with pronunciation. Perfect for visual learners who want to learn languages through everyday life.

SNAP & LEARN
Point your camera at anything. Our AI recognizes objects and creates interactive word tags you can tap to hear pronunciation. Learn words in context, exactly where you encounter them.

SMART FLASHCARDS
Master vocabulary with our spaced repetition system powered by forgetting curve algorithms. Cards appear exactly when you need to review them - no more forgetting what you've learned.

- Automatic scheduling based on your memory patterns
- Visual progress tracking
- Focus on what needs review, skip what you know

SHARE & ORGANIZE
Save your photo cards to albums. Share on social media. Browse vocabulary by real-life scenes and situations.

PRIVACY FIRST
Making a card sends the photo for AI analysis; your cards and study history then live on the device - no account, no cloud library.
