🧠 The core idea
You learn by typing Korean, not tapping choices. Typing forces real recall — that's why it works.
🔄 Daily Review — where do the words come from?
Only from your sets (My Sets — including Library packs you've added). Every word you've practiced carries an invisible timer: answer well → it returns later (1 day → 6 → weeks); fail → it returns today. Daily Review = every word whose timer just rang.
✨ Why do some sets glow?
A glowing set has never been studied. Open it once and its words join your Daily Review rotation.
✅ Full vs. partial mistakes
Full mistake = out of tries or skipped — you'll retype the answer and see it again today. Partial = right on 2nd/3rd try, or a small slip (particle, word form) — half credit, gentler comeback. Dots, spacing and an omitted subject (저는…) never count as a mistake. Typing a correct synonym counts too — with a note explaining the difference.
⭐ Stars & medals
Sentence stars: +1 perfect, +0.5 close (reset via ↺). In reviews, 🥇🥈🥉 track which try you solved each word on. Achievements have levels — click any badge to see all its stars.
🏅 Mastered
5 correct reviews in a row, spread over weeks. One full fail resets the count.
😀 Word emojis
Every word gets a small emoji memory hook automatically (🍂 autumn). Don't like them? Settings → Word Emojis → off.
🎯 Mistake analysis
Every wrong answer is remembered per word. The dashboard's "Practice Mistakes" drills your weakest words across all sets; inside any set, "My mistakes only" appears when there's something to fix.
📖 Stories
AI stories at your chosen TOPIK level, built to reuse words you've already studied where natural. Red words are new to you — hover for meaning (particles are explained: what 에서 actually does), click + to add. Words stop being red once studied or seen ~5 times.
📊 TOPIK estimate
A rough guess from your vocabulary and sentence practice — not an official score. It fades if you pause, like real knowledge. Click it to see every rank.
⚡ AI features
Stories, sentences, smart checking and the ✨ AI set maker need a free Google Gemini key: aistudio.google.com/apikey → Create API key → paste in Settings.
We like the other apps — here's what we do differently:
🟦 vs Quizlet
Their best study modes moved behind a paywall. Here, every mode is free. Honesty: free today isn't a promise of free forever — but the core learning loop will stay accessible either way.
🟩 vs Duolingo
Tapping word bubbles isn't recalling. You type every answer here — and stories explain why it's 에서 and not 에, instead of leaving you to guess.
⬛ vs Anki
Same spaced-repetition science. Minus the 30-minute setup tutorial and the 2006 interface. You clicked one button and were studying.
🟪 vs Memrise & Drops
Vocabulary is the start, not the finish: full sentences with particle-aware grading, dictation, synonym-smart checking, and AI stories that grow with you.
🤝 What nobody else does (that we know of)
Automatic emoji memory hooks on every word 🍂 · mistake analysis that builds "fix-me" drills per set · half-points for particle slips instead of a red X · synonym answers accepted with an explanation · a TOPIK estimate that honestly fades when you slack.
🎁 And the small joys
Level-up fanfares, streak freezes 🧊, ranks from 🐣 to 👑, and…
this button right here 🎊
(the real level-up confetti — consider it a preview). Psst: there are more eggs hidden around. One involves clicking something you see every day. A lot.
