Here’s some early feedback from demo users.
Izayoi Sakurako
High School Student
Lumi’s demo helped me pass my oral exam—teacher said my pronunciation improved ‘like magic’ in just few days!
Thank you Lumi!
Tanaka Mizuki
College Student
As a broke student, I squeezed 2 months’ worth of tutoring into Lumi’s 7-day demo. Game-changer.
Suzuki Kenta
Tech Company Employee
Used the app to ditch my ‘sorry, English a little’ disclaimer. Confidence unlocked... and made practicing feel shockingly real.
Yukimura Chinatsu
Tech Company Employee
Did the demo while commuting. As a non-native speaker, I waste time over-explaining in meetings. Now, my team says I already sound more confident in stand-ups.

Unlock the English You Were Never Taught
For years, traditional education have taught English as a textbook subject—not a living skill. Imagine studying for six years yet never having a real conversation. You master grammar, memorize vocabulary, but when it’s time to speak? Silence.
Here’s the truth: Listening, reading, and writing build knowledge, But speaking turns book knowledge into real life. You haven’t truly learned a language until you can use it in conversation—not just on paper.
The world rewards those who speak: better jobs, seamless travel, friendships across borders. Yet traditional education leaves millions stranded at the threshold of fluency, hesitant and unsure.
That’s why Lumi exists. No more fear. No more "I understand but can’t reply." Just your voice, unleashed.
Let’s talk!
