MindDory: Vocabulary & GrammarVerified tool

MindDory is an AI-native vocabulary and grammar app. Instead of asking you to build flashcards or work through a course, it learns from two things: the words you run into while you read, and the mistakes you make while you write.

The MindDory keyboard works in any app on iPhone and Android. Check a sentence, see how a fluent speaker would say it, or translate it. Grammar checks work in nine languages, and every fix comes with an explanation. The mistakes you keep land in a Grammar tab that shows which of 138 English grammar topics (A1 to C1) keep slipping.

Point your camera at a page of a book, a menu or a screen and vision OCR picks out the words you do not already know. Save a word in one click with the Chrome extension, or connect Claude, Cursor or any MCP-compatible assistant and save words straight from the chat.

AI then does the teaching, not just the typing: new words are woven into short generated stories at your CEFR level, and words that refuse to stick get a Memory Cue, a generated visual mnemonic. Spaced repetition needs no setup: a hard word returns in three days, an easy one in a week, and the second time you call it easy it stops asking.

Learn in 60+ languages; Word Map and CEFR Language Test in eight, across 38,000+ mapped words. Free tier forever. Premium is $7.99 a month or $49.99 a year, with a 7-day free trial on the annual plan.
