Sentence Monster
Practice Words in Sentences
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Sentence Monster helps language learners turn vocabulary into sentences they can actually write.
Knowing a word is not the same as being able to use it. Sentence Monster gives you short sentence-writing practice, checks your answers, and brings back the words you miss, forget, or still cannot use confidently.
Practice with AI-picked sentences tailored to your learning history. Missed, weak, and fading words return through personalized review so you can build active recall instead of only recognizing words.
Key features:
- Sentence-based vocabulary practice
- Personalized review from mistakes and weak words
- AI-generated sentence assignments algorithm
- Writing feedback for sentence accuracy
- Progress and vocabulary insight
- Practice across multiple learning languages
Sentence Monster is built for learners who freeze when writing, even though they already know many words.
Write the sentence, get feedback, and keep repeating the words that need more work.
Supported learning languages: English, Korean, Japanese, Chinese, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Turkish, Indonesian, Vietnamese, and Russian.
