Real conversations. Lasting fluency.

Lumentor is an AI English mentor that talks with you every day, remembers your mistakes until they're fixed, and explains in your own language when you need it — from your very first words to professional fluency.

How Lumentor teaches

More than an app. A mentor in your pocket.

Most apps give you exercises. Lumentor works like a great private teacher: it knows where you struggle, decides what you need next, and proves that you're improving.

Live conversations

Speak out loud with your mentor, in real time, about your life, your work and your goals.

Remembers your mistakes

Said "I go" instead of "I went" last week? Your mentor brings it back in a new conversation until it's fixed.

Explains in your language

Starting from zero? Your mentor explains in your language, then gradually moves you into English.

Progress you can hear

Compare your voice from day one with your voice today. Real evidence, not just streaks and points.

Learning that feels like talking

You just talk. Your mentor is teaching.

  • Gentle corrections. Your mentor repeats the right form naturally, without interrupting your flow.
  • Every session has a goal. Each conversation is designed around what you need to practice next.
  • Help when you're stuck. Say "explain in French", "slower" or "repeat" at any time.
One path, step by step

From your first words to complete confidence.

Lumentor follows the international CEFR levels, from absolute beginner (A0) to mastery (C2). Your level is estimated separately for speaking, listening, reading and writing.

A0First words
A1Simple conversations
A2Everyday life
B1Independent
B2Work & study
C1Professional
C2Mastery

Levels in the app are estimates to guide your learning. They are not official certificates.

Questions

Frequently asked questions

Are Daniel and Sara real people?

No. Daniel and Sara are AI mentors. They speak with you live, remember your progress and adapt to you, and we will always be clear that they are AI.

I don't speak any English. Can I still use Lumentor?

Yes, that's exactly who we're building it for. Your mentor can explain in your own language (French first, more languages coming) and gradually moves you into English as you improve.

When will Lumentor be available?

We're building it now. Join the waitlist and you'll be the first to know, with early access before the public launch.

How much will it cost?

There will be a free plan that includes real conversations with your mentor, and premium plans for daily practice. Prices will be announced at launch.

Which English does Lumentor teach?

Clear, natural American English as the model, while respecting your accent and accepting other valid varieties. The goal is to be understood with confidence.
