Level up your language skills, one story at a time.

Already know the basics of a language but get stuck when reading real books? This app helps you bridge the gap from semi-fluent to fluent without constantly reaching for a dictionary.

Choose from a growing library of books in your target language, and read comfortably with simplified versions of challenging paragraphs just a tap away.

Key features and how it works:

•⁠ ⁠Tackle any paragraph in a book by clicking on it, and instantly switch to a simpler version. Select from multiple "levels" to match your comfort zone. The original text is always visible first, honoring the author’s style and helping you develop the skills to one day read without aid.

•⁠ ⁠Proprietary scoring of paragraph difficulty. Instead of guesswork or AI, we use a carefully engineered algorithm to rank the complexity of each paragraph. This ensures you always see truly simpler text when you need it.

•⁠ ⁠Chapter-focused vocabulary. For every chapter of each book, we have created a vocabulary list. This way, before you start reading a new chapter or a new book, you can practise these words so going through the original texts will become easier. No more randomly learning words that you will not use.

•⁠ ⁠Spaced repetition for words. To facilitate better learning, words you have learned are managed with a spaced-repetition system (SRS). You’ll review new words just in time—never forgetting them as you progress.

Who is this app for?

•⁠ ⁠Intermediate learners. If you grasp the basics of a language, but find native texts just too difficult and find yourself looking up to many words while reading, LanguageLeveler is your bridge to reading success!

Supported Languages:
