Código Morse

MindDory is an application designed for learning vocabulary and grammar using artificial intelligence. Unlike traditional methods that require you to create flashcards or follow a course, MindDory learns from two sources: the words you encounter while reading and the mistakes you make while writing. The MindDory keyboard is compatible with any app on iPhone and Android. You can check sentences, see how a native speaker would phrase them, or translate them. Grammar checks are available in nine languages, and each correction comes with an explanation. Errors you make are collected in a Grammar tab, showing which of the 138 English grammar topics (A1 to C1) you struggle with the most. Use your camera to scan a page from a book, a menu, or a screen, and vision OCR will identify the words you don't know. Save a word with a single click using the Chrome extension, or connect Claude, Cursor, or any MCP-compatible assistant to save words directly from chats. The AI then takes over the teaching process, not just assisting with typing. New words are integrated into short, generated stories tailored to your CEFR level, and words that are difficult to remember receive a Memory Cue, a visual mnemonic. Spaced repetition is automatic: a challenging word will reappear in three days, an easy one in a week, and after the second time you find it easy, it stops repeating. Learn in over 60 languages. Word Map and CEFR Language Test are available in eight languages across more than 38,000 mapped words. There is a free version available permanently. The premium version costs $7.99 per month or $49.99 per year, with a 7-day free trial on the annual plan.
