KaChiKa · Release notes
New features, improvements, and fixes across KaChiKa and KaChiKa JA.
Photo crop fix & startup optimization
Network reliability & photo analysis fix
Thumbnail strip & content difficulty settings
Flashcard creation is most powerful when vocabulary aligns with your proficiency. Version 0.9.5 introduces customizable content difficulty levels — choose between foundational terms or nuanced scene expressions, or let AI adapt automatically. For multi-page textbooks, study guides or restaurant menus, the new thumbnail strip lets you switch effortlessly between recent shots without restarting the camera.

Faster photo analysis & smoother scrolling
Daily review reminders based on memory curves
Generic reminder notifications often ping at rigid times, ignoring whether cards are actually due. In 0.9.2, KaChiKa brings personalized daily review reminders powered by spaced repetition principles — prompting you right when memories approach the forgetting threshold. All review scheduling calculates strictly on-device with zero sign-ups and complete offline privacy.
Instant photo demo & refreshed History with scene dialogues
Memorizing vocabulary in isolation often leaves learners unable to speak naturally in real contexts. 0.9.0 overhauls the History screen: each saved scene now pairs your extracted words with authentic daily sentences and conversational dialogues. Paired with instant photo demos, new learners can see a real photograph transform into a bilingual flashcard in zero seconds.

5-step interactive onboarding & AI scene dialogue
Getting started with a language learning app shouldn't require reading a manual. 0.8.4 reimagines the entire first-time experience with a seamless 5-step intro: see exactly how an everyday photo transforms into key vocabulary and expands into an authentic situational dialogue. We also upgraded the language picker with clear country flags for effortless switching.

Multi-language expansion: French, Korean, Italian, Spanish & Chinese
Polyglots often juggle separate apps for every language they explore. 0.5.0 marks a foundational milestone for KaChiKa Multi: officially launching our multi-language learning matrix with support for French, Korean, Italian, Spanish, and Chinese. Whether reading a menu in Paris or studying Korean signs, one visual capture engine now powers your journey.

Interactive flashcard learning & sentence grammar breakdown
Merely viewing static definitions rarely creates long-term neural recall. 0.3.2 introduces our foundational study system: full-screen interactive flashcard study with active recall testing, alongside deep sentence grammar analysis that breaks down parts of speech, clauses, and conjugations so you master whole sentences alongside individual words.
KaChiKa turns photos into interactive vocabulary cards with words, everyday sentences, short dialogues, pronunciation, and FSRS review scheduling. KaChiKa teaches English, Korean, French, Chinese, Spanish, and Italian; KaChiKa JA focuses on Japanese and JLPT study.
We ship focused releases when a feature or reliability improvement is ready rather than following a fixed calendar. This page records meaningful user-facing changes for both apps.
Open the App Store or Google Play, find your KaChiKa app, and choose Update. Automatic updates may install the release for you when your device is ready.
Making a card sends the photo for AI analysis. Your cards and study history then stay on your device—there is no account and no KaChiKa cloud library.
Choose the app that matches the language you want to learn. Both are free to start on iOS and Android.
