65 English

65% Better. That's Not Marketing. That's Research.

Why do we call it 65? Because peer-reviewed studies show that reading while listening improves vocabulary acquisition by 65% compared to reading alone.

We built an app around this science.

How 65 Works

65 transforms any book into an interactive language learning experience. See every word highlighted as it's spoken, tap unknown words for instant translation, and build vocabulary that actually sticks.

The Science Behind 65

When you see and hear words together, your brain forms stronger connections between spelling and pronunciation. Listening alone? You might need 50-100 encounters with a word to learn it. Reading while listening? Just 7-9.

65 makes this powerful technique effortless.

WORD-BY-WORD SYNCHRONIZATION Unlike basic audiobooks, 65 highlights each word precisely as it's spoken. Follow along naturally and never lose your place. Your eyes and ears work together to accelerate learning.

TAP ANY WORD TO TRANSLATE Don't know a word? Simply tap it. Get instant translation in your language. One more tap saves it to your personal vocabulary list — with the sentence where you found it.

BUILD VOCABULARY THAT LASTS Every word you save includes the context where you learned it. Review with flashcards that show translations, original sentences, and audio. Spaced repetition ensures you remember what you learn.

10 NATURAL-SOUNDING VOICES Choose from 10 premium voices — American and British accents, male and female. All voices sound natural and clear, perfect for learning pronunciation.
