Language apps love streaks and gems; these tools skip all of it. Each one isolates a single high-value chunk: Hangul can be read within days because it's an alphabet of just 40 letters, the 100 most common irregular verbs cover nearly every English sentence you'll meet, and memorizing whole sentences gives you grammar and vocabulary in context at once.

Everything runs in your browser and nothing you type leaves it — the sentence memorizer works with your own text entirely on your device. Open a tool, practice five minutes, close it. That's the whole workflow.

Frequently asked questions

Can I really learn Hangul in a few days?
Reading it, yes — Hangul is a featural alphabet of 40 letters designed to be easy to learn. Most learners read slowly within 2–3 days of short quiz sessions; speed comes with practice.
Which irregular verbs are covered?
The 100 most frequent English irregular verbs, in two sets: the essential 50 (go/went/gone, take/took/taken…) and the full 100. Distractors include the fake regular form (goed) — the exact mistake learners make.
Is my custom text private in the sentence memorizer?
Yes — text you paste is processed entirely in your browser and never uploaded anywhere.
Why memorize whole sentences instead of single words?
A sentence carries grammar, word order and natural word combinations along with the vocabulary — things a flashcard word can't give you. When you need the language later, you recall a ready-made pattern instead of assembling words one by one. That's why the memorizer hides sentences progressively rather than quizzing isolated terms.
Do quizzes actually help me learn, or just measure what I know?
They help — this is the well-documented testing effect: actively retrieving an answer strengthens the memory far more than rereading it. Getting a question wrong helps too, because the correction right after an attempt sticks unusually well. That's why every tool here is quiz-shaped instead of being a list to reread.
What's a good daily routine with these tools?
Keep it to five or ten minutes: one Hangul round if you're learning Korean, one set of irregular verbs for English, then a pass through the sentence you're currently memorizing. Short daily sessions beat a long weekly one — frequency is what moves language into long-term memory.
