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. Just content you love, gradually turning into the language you're learning. BLEND YOUR READING • Smart Blend — AI picks the most useful words and translates them with correct grammar and context • Basic Blend — simple word-by-word blending, unlimited and free • Tap any highlighted word for its meaning and grammar notes ("past tense, first person") and save it • Kindle-style paginated reader with bookmarks and progress tracking SAVE WORDS FROM ANYWHERE • Select text in any app and share it to LingoBlend — translated and saved instantly • Right-click any word on any website with the Chrome extension • Scan menus, signs, and book pages with your camera (OCR) • Import CSV, text, or Anki-formatted lists, or browse 800+ word packs across 25 categories PRACTICE THAT PLANS ITSELF Five games powered by Anki-style spaced repetition — each word comes back right before you'd forget it: • Flashcards with pronunciation audio (Recognition, Recall & Immersive modes) • Matching, Fill in the Blank, Listening Quiz, and Word Quiz • Plus Word Story (Pro) — AI writes a short story from YOUR saved words, read or listen, then take a 5-question comprehension quiz READ GRADED STORIES Stories written entirely in your target language, from beginner (A1) to advanced (C2).
