Learn a language by reading what you actually want to read. LingoBlend takes any text — a news article, a blog post, a book chapter — and blends your target language into it. You control how much with a slider: a light 10% sprinkle as a beginner, up to 80% as you advance. Every blended word is tappable: see its meaning and grammar, save it in one tap, and let spaced repetition do the rest. No isolated flashcard decks. No made-up example sentences.
