Learning a language is hard. Studying a foreign language requires hundreds or thousands of hours, and everyone is busy. Prismatext offers the first effortless method for learning a language: blended-language reading! Now an hour spent reading is an hour spent learning. Using a science-backed method called "Diglot Weave", Prismatext books blend the most useful foreign words and phrases into modern and classic literature for context-based language learning. Prismatext translates more and more of the book you're reading into your target language. This allows the reader to naturally acquire new foreign vocabulary and grammatical rules. See phrases used in-context for improved recall. Repetition and incremental phrase addition allow you to easily learn new words at your desired pace - you can adjust the density at will. Beginner? No problem - tap the translations to see definitions and explainers, as well as the proper pronunciation of the phrase. Advanced? Try a higher level setting and a higher density for faster uptake. Skip the boring practice exercises, games, and gimmicks. Instead, pick up a book you've wanted to read and dive in! ========== PRISMATEXT WORKS Numerous peer-reviewed studies from around the world agree: diglot weave is one of the most effective learning methods for foreign language vocabulary retention.
