Learn vocabulary. Powered by AI. Personalized for you.
Cabu uses AI to create rich, contextual word notes in your native language — so every word you learn actually sticks.
Learning new words shouldn't feel like memorizing a dictionary.
Most vocabulary apps give you a word and a translation. That's it. No context. No pronunciation. No examples. You memorize for a test, then forget everything a week later.
Cabu is different. Every word comes with a complete learning note — AI-generated definition, phonetic pronunciation, real-world examples, and a personalized tip in your native language. You don't just memorize words. You understand them.

I've tried Duolingo, Anki, and Quizlet. Cabu is the first app where I actually remember the words a month later. The AI tips are genius.

As a parent, I love that my daughter can learn English with Vietnamese explanations. She uses it every day on the bus to school.

The dual quiz mode is what hooked me. Meaning mode for quick review, Explanation mode when I want a challenge. Simple but so effective.
