LingoMatrix

LingoMatrix is a web-based language-learning and translation service centered on a 40-word matrix: ten adjectives, nouns, pronouns, and verbs that can be combined into approximately 10,000 sentences. Users describe a learning situation and level, then select words from the matrix or use a randomizer to practise generated combinations.

The service provides sentence translation in multiple languages, including phonetics and read-aloud audio. Its practice and translation content is generated with artificial intelligence, with grammar and common-sense checks applied to the resulting vocabulary, sentences, translations, pronunciations, and audio.

The site is free to use without an account and is supported by advertising. Its public interface is available in English and Spanish.
