About this app

Create your own picture books from the English words you want to learn.

Tsumugi is an English vocabulary app that turns the words you are studying into short, illustrated stories. Instead of drilling flashcards, you read your words inside a story you made yourself - which is how they actually stick.

Made for English learners, ESL and EFL students, kids learning to read, and anyone who has ever memorised a word and forgotten it a week later.

◆ HOW IT WORKS

1. Look up an English word
Type any word. Tsumugi shows the meaning, the part of speech, and its CEFR level (A1 to C2), so you always know how difficult a word is before you study it.

2. Save it to your word list
Build your own vocabulary list. Keep the words you want to work on and remove the ones you have already mastered. Your personal word book, built from real reading.

3. Choose your words and a genre
Pick the vocabulary you want to practise, then choose the kind of story you are in the mood for.

4. Read your story
Tsumugi writes an original four-page picture book using your words. Your chosen words are highlighted in the text, so you can see exactly how each one works in a real sentence.

5. Keep it on your bookshelf
Every story you create is saved. Come back and reread them any time. Repeated exposure in context is what turns a new word into a word you own.

◆ WHY STORIES BEAT FLASHCARDS

Memorising a word in isolation is hard work and it fades fast. Meeting the same word inside a story gives it context, emotion, and a picture to hang on to.

Tsumugi is built around that idea. You are not revising a list, you are reading something you made. And because you choose the words, every book is tuned to exactly where you are in your learning rather than to a generic syllabus.
