ContextVoca vs Learn Katakana

ContextVoca uses AI to turn photos and text into your personal vocabulary list — then quizzes you until you own those words. [SNAP - LEARN - REMEMBER] Point your camera at a book, menu, sign, or any text. Our OCR engine reads it, and our AI extracts the vocabulary words most worth learning. No more manual lookup — just learn. [AI-POWERED WORD EXTRACTION] ContextVoca's LLM engine analyzes your captured text and selects the most meaningful words for your level. It strips away common words and surfaces the ones that will expand your vocabulary fastest. [SMART QUIZ SYSTEM] Our adaptive quiz engine schedules reviews based on how well you know each word. The more you struggle with a word, the more often it appears — so you never forget what you've worked hard to learn. [CONTEXT-BASED LEARNING] Every word is stored with the sentence or phrase it came from. Seeing a word in context is proven to dramatically improve retention compared to isolated flashcards.

Learn the shapes and stroke order of Japanese katakana by tracing each letter with your finger. Built for young children (ages 3–7) and for anyone learning Japanese. Follow the guide A pen-tip marker glides along each stroke from the green start point to the red end point, showing the correct order and direction. Trace along and feel a gentle tap as your line takes shape (on iPhone, and when tracing with Apple Pencil Pro). Every finished character is graded with a familiar Japanese mark: a flower (excellent), a circle (good), or a cross (try again). What you get • All 46 basic katakana, laid out on the classic gojūon chart • Stroke-order guide with numbered start/end points and animation • Pronunciation audio for every letter, plus sound effects • Adjustable difficulty for how strictly your tracing is judged • Apple Pencil support: stroke thickness follows your pressure, and Apple Pencil Pro adds haptics you can feel as you trace (requires an iPad that supports Apple Pencil Pro) • Words while you practice: as you work on a letter, an illustrated word appears with that letter left blank—trace it in to complete the word • Shuffle practice: run through your unlocked letters in random order • My Garden: watch flowers grow as you practice, and compare today's writing with your very first try • Romaji readings to support learners (in non-Japanese languages) Made for little hands and grown-up learners Playful marks and sounds keep children engaged, while a calm, uncluttered layout works just as well for adults.
