How does the AI choose which words I should learn?
Braivo looks at your proficiency level, learning goals, and the topics you care about, then generates word lists ranked by relevance and difficulty. As you study, the AI keeps adjusting — words you struggle with come back more often, and new words match your real progress.
Is Braivo free to use?
Yes. The free plan includes daily AI-generated word lists, natural voice pronunciation, and progress tracking. A premium subscription unlocks unlimited lists, offline mode, and advanced statistics — but you can learn effectively without ever paying.
Which languages are supported?
Braivo supports vocabulary learning in more than 30 languages, including Spanish, French, German, Japanese, Korean, Mandarin, Portuguese, Italian, Turkish, Arabic, and Russian — with new languages added regularly.
How natural do the AI voices sound?
We use state-of-the-art neural text-to-speech that captures native rhythm, stress, and intonation. Every word and example sentence is pronounced the way a native speaker would say it.
Does it work for complete beginners?
Absolutely. When you set your level to beginner, the AI starts with high-frequency everyday words and builds up gradually. Spaced repetition makes sure the foundations stick before harder vocabulary appears.
Can I use Braivo offline?
Premium subscribers can download word lists and pronunciations for offline study — perfect for commutes and travel. Your progress syncs automatically the next time you’re online.
