MindDory is a vocabulary and grammar app that learns from the words you read and the mistakes you make when you write.

Write it right

• Keyboard for iPhone and Android. Check a sentence in any app, see how a fluent speaker would say it, or translate it.

• Every fix is explained. You see why it changed, not only what changed.

• Grammar tab. The mistakes you keep show which topics keep slipping.

Keep the words you meet

• Scan. Snap a page with your camera and pick the words you do not know.

• Chrome extension. Select a word on any web page and save it in one click.

• AI assistants. Connect Claude, Cursor or another MCP-compatible assistant and save words straight from the chat.

Review without setup

Every word and every mistake you keep comes back as a short review, with nothing to configure. A hard word returns in three days, an easy one in a week.

Learn in 60+ languages. Grammar checks work in nine. Free on iPhone, Android, the web and Chrome, with an optional Premium plan.
