Nebula

Pick your two languages.
Choose the two languages your family speaks. Read and listen to the same stories in both, and switch between them with a tap.
Quiet picture books in the languages your family speaks. Made for reading aloud—on a couch, on a lap, before sleep.
Choose the two languages your family speaks. Read and listen to the same stories in both, and switch between them with a tap.
Read to your child in your language. Your partner reads in theirs. Your child gets to enjoy the same stories with both of you, in both languages.
When your hands are full, put on an audiobook. The stories come with audio in both your chosen languages, so your child can listen in either one.
Nebula's library grows every week. Small stories for the very little ones. Longer adventures for early readers. Series that follow the same characters across many nights.
Black Sheep
1 / 5
Recurring characters, familiar worlds. Kids fall in love with a black sheep, or a llama, or a small brave mouse — and follow them across many books. New stories in each series arrive week after week.
First words for the youngest. Simple stories for toddlers. Longer chapters for children starting to read on their own. The library grows with your child, not past them.
Bedtime, big feelings, family visits, the first day of school, the small everyday things. Stories built for the moments you'll actually live through — and want to read about, together.
My wife reads to him in Dutch. I read to him in Spanish. We wanted the same beautiful stories to belong to both of us.
We couldn't find enough of them. So we made Nebula.
A cuddle on the couch. A long drive to Grandma’s. Make room for a story, in both your family’s languages.
At home
Pull them onto your lap. Open a picture book. Point at the pictures, try the funny voices, hear “again!” in two languages. Nebula puts a whole library of shared moments in your hands.
On the go
Headphones on. Story on. Turn the journey into an adventure with audio in both your chosen languages. Their favourite characters come along, and a little piece of home travels with them.
Three full books, free, forever. While we test and improve Nebula, the whole library is free too.

The things parents ask us most — answered plainly.
Hi, I'm Ariel. I'm a father living in the Netherlands. My kids are growing up between languages, and I wanted them to hear the same stories in the voice of every person who loves them. Nebula is a small project, made by a small team. We read these books to our own kids before anyone else.
Every story starts with a writer. A real person, sitting down with an idea and a coffee. From there, we use AI to help with illustrations, translations, and audio narration. Then a person reads every page, in every language, before it's published. If something feels off, we fix it. If it can't be fixed, we don't publish it.
We think so, but we'd rather you decide. The first three books are free, no account needed. Every story is short, quiet, and built to be read aloud, with one small fun tip per page for the grown-up (optional). We make books we'd want to read to our own kids — slow, warm, and honest. Not loud, not flashy, not trying to teach. Just stories.
It's screen time. We won't pretend otherwise. But not all screen time is the same. A child watching cartoons alone is different from a child listening to a story in their grandmother's language, on a parent's lap. Nebula is built for the second kind. Sessions are short. There's no autoplay. Nothing tries to keep your child watching past the end of the story. When the book ends, the screen quiets down. That's on purpose.
Roughly ages 0 to 5, but it depends on the child. Babies and toddlers love the sound of a voice, the rhythm of a story, the same book over and over. Older children (3-5) start to follow the narrative, ask questions, repeat words in both languages. Our books are short, simple, and written to be re-read, because that's how children actually fall in love with stories. If your child is older than 5 and still wants to be read to, even better. We won't stop you.
Not from Nebula alone. No app teaches a child a language, people do. What Nebula can do is keep a language alive in your home: through stories, through the sound of your voice, through the small ritual of reading together. Children who grow up hearing a language read to them, by someone who loves them, are far more likely to keep it as their own. That's what we're built for.
Nebula works best on Apple and Android tablets. It can also be used on phones when you are on the go.
Nebula launches with five languages: English, Spanish, Portuguese, Italian, and Dutch. For all languages, every translation is reviewed before publishing. If something reads awkwardly in your version, please tell us, we read every message, and we fix what we can.
Yes, slowly. We'd rather do five languages well than fifteen languages badly. German, French, and Mandarin are the most requested so far, we're listening. If your home language isn't on the list yet, write to us. We keep track of every request, and it helps us decide what comes next.
Nebula has three ways to read:
Start free. Upgrade if you want more. Cancel whenever. Simple.
You don't need a trial — the first three books are free, no account, no card, no commitment. The whole library is free while we test and improve Nebula. If you decide to subscribe later, you can cancel anytime, from the app or by emailing us. No phone calls, no "are you sure?" pop-ups, no dark patterns. If Nebula isn't right for your family, we'd rather you leave easily and remember us kindly.
No ads. None. Not now, not ever. We don't collect personal data about your child, no name, no age, no reading history tied to a profile. The only thing we know about your family is what you tell us when you sign up: an email, a payment method, and which language pairs you read. That's it. We don't sell data. We don't share data. We're a subscription business, not an advertising one, and that's on purpose.
In the app, open Settings, choose Delete account, and confirm with your password. If you can't access the app, you can ask us to delete it for you. The full steps and details about your data are on our account deletion page.
Free on iOS and Android. Three books are waiting on the shelf — pick a language pair and meet a sleepy fox.
