Stop studying conversations. Start having them.
Traditional language apps are great at teaching vocabulary and grammar. But knowing the words isn't the same as being able to use them.

From “What am I going to say?”
To “I've practiced this before.”
Imagine walking into a real conversation knowing you've already practiced something similar. You don't need a perfect script. You need enough practice to feel comfortable responding.

I built Lumina because I lived this story.
During COVID, my family moved from Santiago, Chile to the Bay Area in California. Overnight, I went from a country where I understood every joke, every teacher and every cashier — to one where I barely understood anything.
I didn't speak the language well yet. I froze in conversations, dreaded raising my hand in class, and replayed every awkward interaction in my head for hours afterward. The apps I tried taught me how to say "the cat is on the table" — but never how to actually talk to a real person.
That's why I built Lumina. A tool I wish I'd had when I landed — one that rehearses the conversations that actually scare you, in your own accent, at your own pace, with a little of your native language mixed in so you never feel lost.

Questions, answered.
What is Lumina?
Lumina lets you practice realistic spoken conversations in a new language with an AI conversation partner, so you rehearse a situation before you live it.
Is Lumina a replacement for school or a language course?
No. Lumina is speaking practice. It works alongside a course, a class, or self-study — it's the part where you actually use what you learned. It is not immigration, legal, or academic advice.
What languages can I practice?
Eight: English, Spanish, French, German, Italian, Japanese, Mandarin and Arabic — each with its own characters.
Do I need to be advanced?
No. You tell Lumina your level — from never spoken it before to fully comfortable — and the conversation adapts to you.
How much time do I need?
About 5 minutes a day is enough to keep your streak going and build consistency.
Do I need a credit card for the free trial?
No. The 7-day free trial requires no credit card. You only pay if you choose to continue after it ends, and you can cancel anytime.
Your next real conversation is coming.
Practice it before it happens.
