AI tutor for speaking practiceKnow the words.Now speak them.
Talk with a tutor that listens, corrects you as you speak, adapts to your level, and remembers how you learn.
A demonstration of a Lumen session. The learner says they wake up at seven and go to gym, and that it help them have energy. The tutor corrects both mistakes, to “go to the gym” and “it helps me”, saves them, teaches the word “refreshed” for “descansado”, and sets one piece of homework.

Common questions
Is it really free to start?
Yes. A 4-minute spoken placement with Lumen, then a plan built around how you actually speak. No card, no account, nothing to install. Lessons after that need a plan — you see the price once you know your level, and a first plan starts with 7 days free.
I used to speak it. Is this for me?
Yes. The placement finds where you actually are, so nothing starts from zero, and your tutor works at that level from the first class.
Which languages can I learn?
English, Spanish, French, German, Italian, Portuguese, Japanese and Mandarin Chinese. You can pick from more than eighty native languages when you start, so explanations come back in your own.
Can I cancel?
Any time, from your account settings. Cancel before your renewal date and you keep full access until the current period ends.
How long is a session?
Classes are 5, 10 or 15 minutes and you schedule them yourself. Role-play scenes are five minutes. The placement conversation is about 4 minutes.
How is Lumen different from other language apps?
Most language apps make you tap; Lumen makes you talk, out loud, with an AI tutor. And most AI apps just chat: no memory, no method, no plan. Lumen plans every class around your goal, pitches it at your level, corrects you as you speak, saves what it hears, and remembers it next time.
