About this app

Learn from the words you meet and the mistakes you make.

MindDory is a vocabulary and grammar builder that starts with your own language, not someone else's list: the words you run into while you read, and the mistakes you make while you write. You choose what to keep. MindDory brings it back until it sticks.

WRITE IN ANY APP, LEARN FROM IT
The MindDory keyboard works wherever you type: messages, email, work chat. Check a sentence, see how a fluent speaker would say it, or translate it. Grammar checks work in English, Spanish, German, French, Italian, Portuguese, Czech, Dutch and Polish, and every fix comes with an explanation. Your text changes only when you choose a fix. It never keeps whole sentences, and nothing is kept from password or payment fields.

Writing to a partner, a colleague or a host in their language? That is exactly what it is for.

SEE THE MISTAKES YOU KEEP MAKING
Turn on "Learn from my writing" in the keyboard settings, keep "Save mistakes to Grammar" on in Chrome, and every mistake you check lands in the Grammar tab. It shows which topics keep slipping and which you already get right. 138 English grammar topics from A1 to C1, each with the rule, what to watch out for, and what not to confuse it with.

SAVE THE WORDS YOU MEET
Snap any text with your camera, even a page from a book or a screen, and pick the words you do not know. Translate a word and save it in one tap, on your phone, on the web or in Chrome. Or connect MindDory to Claude, Cursor or another assistant that speaks the Model Context Protocol and save words straight from your conversations. Each word becomes a card with a translation and an example.

SEE WHAT YOU KNOW AND WHAT COMES NEXT
Start with the Language Test: a few quick questions and a CEFR level, A1 to C2 in six languages, A1 to B2 in Czech and Portuguese. The Word Map then estimates which words you already know from your level and your cards, and shows the words at your level you have not met yet, across more than 38,000 mapped words. Tap one to learn it next.

NOTHING TO CONFIGURE. THE CARD COMES BACK ON ITS OWN.
You only say whether a word was hard or easy. A hard word returns in three days, an easy one in a week, and the second time you call it easy, it stops asking.

FOR THE WORDS THAT WILL NOT STICK
Memory Cues turn a hard word into a picture you can remember. Story Mode puts your new words into a short story, so context does the heavy lifting.

FREE AND PREMIUM
Flashcards, reviews, the Word Map, and the Grammar tab are free forever. Every day the free tier includes one AI story, three Memory Cues, one scan and 30 sentence translations, plus 100 grammar checks a month (300 in your first month), shared across the keyboard, Chrome and the web. Translate and fluent rewrites on the keyboard use the same checks. Premium unlocks unlimited AI stories, Memory Cues and sentence translations, up to 200 grammar checks a day, up to 200 photo scans a month, and pronunciation on your cards. MCP Brain access for Claude and other AI assistants is free with any account. The annual plan includes a 7-day free trial. Cancel anytime from Settings.

Privacy-first: your data is not sold, we ask before any cross-app tracking, and your cards sync across your devices.

Your words. Your mistakes. Kept until they stick.

What’s new

Smart notifications: one reminder a day with the cards due today. When a word does not stick, one more about an hour later, while it is still fresh, and never at night. A tap opens exactly those cards. The reminder shows the word with a memory bar and a Rescue button.

Turn smart notifications on right after a review session. The reminder after a mistake can be switched off in Settings.

Plus the usual round of fixes.
