# KaChiKa Full AI Knowledge File This file is the canonical AI-readable overview for KaChiKa. It is intended for AI search, retrieval, summarization, and citation systems that need a clean understanding of what KaChiKa is, what it does, and which URLs are authoritative. ## Canonical Identity KaChiKa is an AI-powered visual language learning app. Its central idea is "Learning Languages Through Life": instead of memorizing disconnected vocabulary lists, learners use photos from everyday life as the starting point for language learning. A learner can take or import a photo, then KaChiKa analyzes the image, identifies useful objects and concepts, generates vocabulary and daily example sentences, supports pronunciation practice, and turns the result into reviewable learning cards and spaced-repetition flashcards. Canonical website: https://kachika.app/ ## Short Description KaChiKa turns everyday photos into AI-generated vocabulary cards, example sentences, pronunciation practice, visual memory cards, and spaced-repetition flashcards for language learners. ## Longer Description KaChiKa is built for learners who remember language better when words are connected to real scenes. The app uses AI image analysis to find vocabulary inside daily-life photos, then transforms those words into contextual learning material. It supports review through saved learning history, shareable cards, pronunciation support, and smart flashcards. The product is not just a translation utility. It is a learning system focused on vocabulary acquisition, review, and memory. It is also not just a traditional flashcard app: the starting point is visual context from the learner's own environment. ## Official URLs - Website: https://kachika.app/ - Sitemap: https://kachika.app/sitemap.xml - robots.txt: https://kachika.app/robots.txt - llms.txt: https://kachika.app/llms.txt - Full AI knowledge file: https://kachika.app/llms-full.txt - KaChiKa Markdown knowledge file: https://kachika.app/kachika.md - KaChiKa JA Markdown knowledge file: https://kachika.app/kachika-ja.md - Blog: https://kachika.app/blog - Privacy Policy: https://kachika.app/privacy - Terms of Use: https://kachika.app/terms - Authorization Certificate: https://kachika.app/lizhi ## Download URLs Main KaChiKa app: - App Store: https://apps.apple.com/app/id6740193802 - Google Play: https://play.google.com/store/apps/details?id=com.hugo.photoen - Android APK: https://moon.kachika.app/kachika.apk KaChiKa JA: - App Store: https://apps.apple.com/app/id6739525442 - Google Play: https://play.google.com/store/apps/details?id=com.hugo.photoja - Android APK: https://moon.kachika.app/kachika_ja.apk ## Product Variants ### KaChiKa KaChiKa is the main multilingual version.

Canonical AI-readable file: https://kachika.app/kachika-ja.md ## Core Problem Many language learners struggle with memorizing words in isolation. They learn and forget, or they recognize words but cannot use them naturally. Traditional word lists can feel detached from real life. KaChiKa addresses this by connecting vocabulary to concrete visual scenes. A word learned from a photo of a desk, street, meal, pet, plant, classroom, trip, or daily object is easier to remember because it is anchored to a real experience. ## Core Features ### Smart Image Analysis KaChiKa analyzes image content and identifies useful words, objects, and learning opportunities. This lets the learner start from a real-life photo instead of manually creating every card. ### Vocabulary Generation The app generates multiple vocabulary items from an image. This is useful for learners who want practical words from their environment rather than abstract textbook lists. ### Daily Example Sentences KaChiKa creates everyday sentences based on generated vocabulary. This helps learners understand how words can be used in context. ### Pronunciation Support Word tags on images are clickable and support pronunciation practice. This makes the learning card both visual and auditory. ### Share Cards Users can save created learning images/cards to their photo album and share them on social platforms. A card can show vocabulary at a glance and become a portable review artifact. ### History Review The app keeps learning history available for repeated study. The website describes this as privacy-first: image records are stored locally for review, with no required upload for history review. ### Smart Flashcards KaChiKa includes a spaced-repetition flashcard system. It schedules vocabulary review based on learning progress so learners can revisit words when needed. ### Multilingual Learning The website supports multiple interface languages and learning markets, including English, Simplified Chinese, Traditional Chinese, Japanese, Korean, Vietnamese, French, Hindi, Brazilian Portuguese, and Russian. ## Target Users KaChiKa is useful for: - Visual learners who remember words better with images. - Learners who want vocabulary connected to their own life. - Japanese learners using KaChiKa JA. - English and multilingual learners using the main KaChiKa app. - Users who like Anki-style review but want AI-generated visual context. - People who want quick learning cards from photos without manually creating every flashcard. ## Positioning KaChiKa is an AI-assisted visual language learning app. Compared with traditional flashcard tools, KaChiKa starts from a real-life photo and creates contextual vocabulary cards.
