Sentence Monster: turn words into sentences
Sentence Monster is a language-learning service that helps you turn vocabulary you recognize into sentences you can write. Practice with AI-generated sentence prompts, answer feedback, and personalized vocabulary review on the web and in the Sentence Monster iOS app.
It is designed for learners who know individual words but find it difficult to use them in a complete sentence. You actively build an answer, check the feedback, and revisit words that need more practice.
How to learn with Sentence Monster
Sign in or create an account, choose the language you understand and the language you want to learn, then start sentence practice. Use the prompt to build your answer in the learning language, with word tiles or text input where available.
Submit your answer and review the feedback. The service uses your learning history to bring back missed, weak, and fading words in later exercises. Progress and vocabulary views help you see what you have practiced.
15 learning languages
English, Korean, Japanese, Chinese, Spanish, French, German, Italian, Portuguese, Dutch, Polish, Turkish, Indonesian, Vietnamese, and Russian.
