Context first
Words appear inside short stories at your level, not on a list. Reading builds memory that flashcards can't.
Vokibi turns short English stories into a daily reading habit your vocabulary actually grows with. Meet new words inside a story; lock them in with smart, topic-based review.
Most apps make you grind flashcards out of context, then forget the words a week later. Vokibi flips the order.
Words appear inside short stories at your level, not on a list. Reading builds memory that flashcards can't.
For topic-based vocabulary study, the SM-2 algorithm schedules each word for the moment you're about to forget it.
No hearts to refill, no fake levels, no daily goal shaming. Learn at your real pace — your time is respected.
From A1 beginner to C2 advanced — adventure, mystery, classics, sci-fi, fables. Pick the genre that pulls you in.
Every word you save lives in your personal notebook — organized in folders that make sense to you. It's a collection that grows with you, not a to-do list.
Travel, food, work, technology — each topic set runs on the proven SM-2 spaced repetition algorithm. Four quiz types alternate so words stay sharp.
Travel & airport, business meetings, restaurants, small talk — practical phrases with native audio you'll actually use. A daily word and a daily quote keep English in your day.
Levels, XP, and consecutive-active-day streaks keep motivation steady without turning learning into a leaderboard. Watch real progress build up.
Word meanings appear in your own native language, in-line, the moment you tap.

Yes — stories, topic study sessions, and your progress all work offline. Vokibi is offline-first: it syncs when you have signal and never gets in your way when you don't.
SM-2 is a spaced repetition algorithm developed by SuperMemo in the 1980s. After each review it adjusts the interval before you'll see that word again, based on how well you remembered it. The better you know a word, the further out the next review pushes — so you spend your study time on the words you actually need to see.
In Vokibi, SM-2 powers the topic-based vocabulary study. Story reading and the notebook are separate, untimed surfaces — read and save freely, no algorithm pressing you.
