Cozy Cabin
Your English partner living on the moon
Tonight, your English stops getting stuck.
Just speak. LUNA listens to your words, remembers them, and answers back. The more you talk, the closer you become.
— I remember every English word you've said to me.
Just talk
No buttons to think about. No sentences to plan. Just speak.
She remembers
Topics you shared, favorites, even your speaking habits — she keeps them all.
3 days, fully free
Try everything from day one. No surprises, no friction.
Inside the app
Fun keeps you going — that's how your English grows.
Conversations you want to start, memory that holds onto everything you said. The longer you stay, the more your English grows.
Speak
Never run out of things to say.
No more "what should I talk about?" — LUNA brings up the topic, so you can start the moment you sit down.
- LUNA opens up the topics for you
- Adapts to your mood and your day

Never stuck
When the words don't come, they appear.
"How do I say this?" — the right phrase shows up right there. Say it out loud, and the conversation keeps going.
- Hints appear the moment you get stuck
- Lost? Switch to your own language anytime
- Read it out and you're back in flow

Grammar and pronunciation, polished.

Can I use it if my English is weak?+

Do I have to use it every day?+
Not at all. Even short repeated conversations help LUNA remember you, and speaking gets easier over time.
I'm nervous about making mistakes.+
You're safe. LUNA never rushes you toward a 'correct' answer. She receives whatever you can say.

Every feature is free for 3 days starting the day your account is created. You'll start the trial inside the app on first launch.
