This is a simple and very easy-to-use English sentence learning app for learners of all levels. Our app is based on the 10,000-word sentence-building exercise known as the “Thousand-word test” or the “Milgram test.” This test is used by most ESL teachers and learning specialists to help students build their vocabulary and improve their grammar. Our goal is to make the learning process easier for you.

You can use our sentence builder to create your own sentences in English. The sentences you create will be checked and corrected by our AI algorithm.

You can also use our app to learn English sentences from a number of different sources such as news articles, documents, and academic papers.
