Wordsprout: Vocab Trainer

Learn vocabulary the scientific way — spaced repetition that adapts to you.

Wordsprout is a beautifully simple vocabulary trainer built entirely around one goal: helping words stick in your long-term memory.

Under the hood, Wordsprout uses FSRS — the same modern, scientifically-backed spaced repetition algorithm that powers today's most effective memory apps. Every word you study is shown to you right before you're about to forget it, so your reviews are always efficient and never wasted.

HOW IT WORKS • Add your own words, or plant a ready-made starter pack (Top Verbs, Days & Time, Food & Drink, and more — 12 packs, 300+ words) • Flip each card, rate how well you remembered it, and let the algorithm handle the rest • Tap any word on the front of a card to hear its pronunciation

GROW AS YOU LEARN • Earn XP for every review and level up from Seed all the way to Evergreen • Build a daily streak and hit your personal review goal • Chain five correct answers in a row for a combo celebration

TRACK YOUR PROGRESS • See exactly how many words are due each day for the next two weeks • Watch your words grow from seed to sprout to fully bloomed • A GitHub-style activity heatmap of your study history

WORKS OFFLINE Study anywhere — on a plane, on the subway, without signal. Your progress syncs automatically the next time you're online, so your data is always safe and available on every device you sign into.

Wordsprout is completely free, with no ads and no subscriptions. Just a simple, focused tool for growing your vocabulary — one seed at a time.
