The best way to learn a language is to speak it
Luna is a voice-first AI language tutor you can hold a real conversation with.
Why voice-first language learning works
You speak, not tap
Real fluency comes from producing the language out loud. Luna listens to your pronunciation and phrasing and responds like a patient conversation partner.
Corrections in context
When you get a gender, tense or word order wrong, Luna explains why in plain language and has you say it again correctly.
Practice anywhere
Just call or WhatsApp Luna at +1 (231) 879-5862. Practice Spanish on your commute or English while cooking — completely screen-free.
How a Luna language session works
- 1
Just ask for a language
Say "teach me Spanish" — or any language — and Luna starts the lesson on the spot. No course to pick, no levels to unlock.
- 2
Start talking
Luna opens a scenario — ordering food, a job interview, small talk, exam prep — and keeps the conversation going at your pace.
- 3
Get feedback and keep your progress
Luna corrects mistakes as you go, and with a free account it tracks your progress and returns to your weak spots in the next session.

Luna AI vs Duolingo: why speaking wins
Duolingo is a game about a language. Luna is a conversation in it. Just ask Luna to teach you a language and the lesson starts — no course to unlock, no streak to protect.
| Duolingo | Luna AI | |
|---|---|---|
| Real conversation | Tapping tiles, matching words and short scripted prompts | Open-ended spoken conversation that adapts live to what you say |
| Time actually speaking | A few seconds of repeat-after-me audio per lesson | Whole sessions where you do most of the talking |
| Mistake feedback | A buzzer and a red X | Explains exactly why it was wrong, then has you say it correctly |
| Getting started | Pick a course, grind the unlock path in order | Just say 'teach me Spanish' and the lesson begins instantly |
| Your own material | Fixed course content only | Bring class notes, vocab lists, PDFs, a textbook or a Quizlet set |
| Progress tracking | Streaks, gems and leaderboards | With an account, Luna remembers your weak spots and picks up where you left off |
| Screen required | Yes — the whole experience is visual | No — study by phone call or WhatsApp, fully hands-free and accessible |
Best app to learn Spanish by speaking
Most learners can read Spanish long before they can hold a conversation. Luna closes that gap: it asks questions in Spanish, listens to your answer, corrects gender agreement, verb conjugation and word order, and switches to English explanations whenever you're stuck. Practice ordering at a restaurant, handling a phone call, or discussing your job — the same situations you'll actually face.
Best app to learn English as a second language
For ESL learners, Luna is a patient speaking partner that never gets impatient with mistakes. Drill everyday phrases, professional English for meetings and interviews, or exam-style responses for IELTS and TOEFL speaking sections. Luna adjusts vocabulary to your level and pushes you slightly beyond it each session.
Conversation practice without the pressure
The hardest part of a new language is the first spoken sentence in front of another person. Luna gives you unlimited low-stakes reps — nobody is judging, you can ask for a repeat as many times as you need, and you can restart a sentence until it feels natural.
Frequently asked questions
Is Luna a good Duolingo alternative?
If your goal is speaking, yes. Duolingo is strong for vocabulary drilling and daily habit-building; Luna is built for real spoken conversation, corrections, and explanations — the part most apps skip.
Which languages can I practice?
Just ask. Say 'teach me Spanish' — or French, English, German, Italian, Portuguese, Korean and more — and Luna starts the lesson right away. Nothing to request or unlock.
Does Luna track my progress?
Yes, with a free account. Luna remembers the words and structures you struggled with, tracks your study streak and picks up where you left off in the next conversation.
Can I practice without a screen?
Yes. Call Luna's phone number or start a WhatsApp voice call and have a full spoken session hands-free — great while commuting or walking, and fully accessible for blind and low-vision learners.
Can Luna use my own class material?
Yes. Upload notes, PDFs, vocabulary lists or a Quizlet link into a Study Library and Luna will ground the conversation in exactly what you're studying.
Is it free to try?
Yes. Every account starts with free monthly study minutes — no credit card needed to have your first conversation.
