NARRA · 言境
Let language grow in story worlds,
naturally
A multilingual interactive world that remembers every choice you make and grows with your level. You follow the story; the language follows you.
How it works
Research settled this long ago: large amounts of meaningful, understandable input beats memorising word lists.
Exactly the right difficulty
You understand most of the story, and it sits just a little above your level — that is i+1 comprehensible input: never boring, never drowning.
Written by AI, for you
Every chapter is generated live from your interests, level and vocabulary. Tap a word you do not know and its meaning appears beside the line, without breaking your reading.
Choices change the world
At the end of each chapter you make a real choice, and the story remembers it. Dozens of chapters later, that decision still echoes.
Vocabulary comes back naturally
Words you saved reappear in new contexts later in the story. You remember not a translation, but what the word means inside the story.
NARRA is not a vocabulary drill app
- Not flashcards and word lists
- Not drills and streak punishment
- Not fixed texts with exercises
- It is a world that remembers your choices
- It is a story you can always just about read
- It is vocabulary growing out of the plot
When “I want to know what happens next” replaces “I must finish this exercise”,
staying with it no longer takes willpower.
Begin with three worlds
Each world is a serial written for you. Pick an entrance, and the story is never the same again.
