Snap a Photo — Everything Around You Becomes Flashcards
Learn languages through daily life: AI makes the cards, spaced repetition schedules the reviews.
Features
Snap it, and it knows the words
Photograph anything around you—AI recognizes the image, pulls out multiple words, and writes everyday example sentences. Tap any word tag to hear its pronunciation.
Reminds you right before you forget
Spaced repetition (SRS) built on the Ebbinghaus forgetting curve schedules each flashcard review just as a word starts to fade—turning ‘looks familiar’ into ‘know it cold.’
Your cards, saved straight to Photos
Save your vocabulary cards to your photo library to flip through anytime, or share them to social media in one tap. Build your vocabulary together with friends.
Your photos stay on your phone—no upload
Every image is stored locally on your device, with nothing uploaded anywhere. Even offline, revisit every card you’ve made anytime. Privacy first.
Why I Built KaChiKa
Throughout my language learning journey I kept learning words and forgetting them—wanting to speak, but stuck. Visual memory changed that: once abstract words became pictures, they stuck. What if language learning just lived inside daily life? That question became KaChiKa—so others can learn in a natural, visual, context-rich way.

I built something similar with Coze before, but a real app is so much better. The UI feels great too. Hope it can extract and track grammar points someday. Huge thanks to the developer!
