About this app
Inception is a tool for opening an English sentence.
Not vocabulary drills, not phrase imitation — a way to look at how a sentence is built. 480 curated English sentences, each unfurled with a four-layer color analysis that shows where the subject, verb, object, and modifier sit, and how they connect.
■ Four-Layer Color Grammar
A color system rooted in classical sentence-pattern analysis. Subjects in blue, verbs in red, objects in green, modifiers in gray — the structure becomes visible the moment you unfurl.
■ 480 Curated Sentences
Sentences picked one by one, sorted into beginner, intermediate, and advanced. Start with today's five, then browse the library by topic.
■ Key Phrases & Grammar Tips
A short note for every sentence. Small details that turn a glance into understanding.
■ Four Languages
Korean, English, Japanese, Simplified Chinese. Translations, key phrases, and tips — all four languages, applied instantly when you switch.
■ Daily Reminder
One sentence a day, at a time you choose.
■ Reads Like a Book
Paper, ink, gold — an editorial design built to be kept, not consumed.
■ Stats and Bookmarks
Today's pace, cumulative learning, favorites. A quiet record of your study.
Ads are shown (banner, interstitial, app-open). A lifetime Premium tier (ads removed forever + every sentence unfurled forever) will be enabled in a future update.
