Meet Cleo the Cloud

We wanted bedtime to feel a little more special. So we built a friendly little cloud named Cleo who can tell your kid a brand new story about their favorite things, sing them a lullaby, and actually get to know them along the way. She lives right inside the Sleepytale bedtime app, and she is always happy to see your child.

Who Is Cleo the Cloud?

Cleo is Sleepytale's AI bedtime companion. She is a warm, curious little cloud who talks with your child, learns what they love, and turns all of that into personalized bedtime stories, lullabies, jokes, and more. Think of her as part storyteller, part singer, part silly joke teller, and part thoughtful friend, all wrapped up in one fluffy cloud.

She is not a chatbot. She is not a search engine. She is a companion built specifically for kids, designed to make bedtime feel personal and fun. Unlike generic audiobook apps or YouTube sleep videos, Cleo does not play the same content on repeat. She creates something new every night based on what your child loves.

What Can Cleo Do?

She tells bedtime stories (starring your kid).
Cleo does not pull from a library of pre-written tales. She creates brand new stories for kids on the spot, built around the things your child actually cares about. Dinosaurs, space, a magical bakery run by cats. Every story is different and every story is theirs.

She sings lullabies.
When it is time to wind down, Cleo can sing soft, original lullabies for children to help your little one drift off. Not the same three songs on repeat. Fresh, gentle melodies that make the end of the day feel cozy and calm.

She tells jokes.
Kids love a good silly joke, and Cleo has plenty. She knows how to get a giggle out of a five year old and she is not afraid to be a little goofy about it.

She teaches little lessons along the way.
Whether it is kindness, bravery, sharing, or understanding big feelings, Cleo naturally works meaningful lessons into her stories and conversations. It never feels like a lecture. It just feels like part of the adventure.

She remembers.
This is the part parents love most. Cleo remembers your child's name, their favorite animals, the characters they have made up, and the stories they have enjoyed. When your child comes back the next night, Cleo picks up right where they left off. Like a real friend would.

How It Works

Step 1: Open the app.
Launch Sleepytale on your phone, tablet, or browser. No setup or downloads beyond the app itself.

Step 2: Your child says hi to Cleo.
Cleo greets your child by name and asks what kind of adventure they are in the mood for tonight. A story about dragons? A lullaby about the ocean? She follows their lead.

Step 3: Cleo creates something just for them.
In seconds, Cleo crafts a brand new story, lullaby, or joke tailored to your child's interests. She narrates it with her own voice and brings it to life.

Step 4: Cleo remembers for next time.
Everything your child shares, from their favorite characters to the stories they loved and the topics they keep coming back to, Cleo saves for the next bedtime so each night builds on the last.

Why We Built Cleo

Stories alone were not enough. Kids do not just want to be told a story. They want to be part of it. They want someone to talk to, someone who cares about the little things that matter to them. That is why Cleo exists. She is a friendly voice that makes your child feel seen and ready for sleep.

We built her because we believe bedtime should feel like the best part of the day, not the hardest. As parents ourselves, we know what it is like when the routine feels rushed or when you just need a little help winding things down. Having a companion who knows your child, who remembers what they love, who can make them laugh or help them relax, that changes everything.

Safe, Simple, and Made for Kids

Cleo was designed from the ground up for children. Every word she says is filtered for age appropriate content. She does not show ads, she does not collect unnecessary data, and she does not try to keep your kid awake longer. Her whole job is to make bedtime wonderful and then help them fall asleep. Cleo was built with children's privacy in mind, so parents can feel confident their child is in a safe, trusted space.

Parents stay in control the entire time. You can see what Cleo and your child talked about, and you can customize what kinds of stories and topics Cleo explores. Nothing happens behind closed doors.
