New: Watch & Learn

Watch how the world works.

See it, not just hear it

Water cycles, volcanoes, planets, plants, planes and more, drawn and animated for young eyes.

KoKo explains every lesson

A real recording in KoKo's voice plays as the animation runs, in words made for ages 5 to 10.

Built for parents' trust

Some questions belong to you.

Faith, bodies, where babies come from. KoKo doesn't answer these for your family. It kindly sends your child back to you, and lets you know it happened.

Your child
Where do babies come from?
KoKo
That's a really special question! Your grown-ups are the best people to talk to about that one. Want to ask them tonight?
In your dashboard: a conversation starter for "bodies and where babies come from".

Two safety checks on every answer

Fast filters catch known risks instantly. A second check understands tricky phrasing, like "pretend you're a scientist" or "it's for a story".

A dashboard behind your PIN

Read every conversation, review flagged topics, and set screen time. Your child can't get in without you.

Never cut off mid-sentence

When time is up, KoKo finishes its answer and says a warm goodbye. No sudden stops, no meltdowns.

No ads, no tracking, no strangers

KoKo talks only to your child. There is no chat with other users and nothing to buy without a grown-up's answer to a math question.

KoKo Weekly

Every week, a short note on what they explored.

What they explored, which lessons they watched, the Fun Facts they read, and questions worth talking about together. Flip back through earlier weeks any time. Built on your phone from your child's activity. Nothing is sent anywhere.

Questions parents ask

Good to know.

What age is KoKo for?

Children aged 5 to 10. KoKo adjusts its words and answers to your child's age, so a 5-year-old and a 9-year-old hear different explanations.

Does my child need to read or type?

No. KoKo is voice-first. Your child taps the button and talks. Highlighted words help early readers follow along, but they are never required.

What happens with sensitive questions?

Topics like faith, politics, bodies and dating are gently sent back to you, and you see a conversation starter in your dashboard. Anything that could be unsafe is never answered, and it is flagged for you.

What do I get for free?

Five KoKo Answers every day, all 500+ Fun Facts, two Watch & Learn lessons in every topic, and the Discovery vault. Pro adds unlimited questions, all 45 Watch & Learn lessons, bedtime stories, KoKo Weekly and up to 3 child profiles.

What is Watch & Learn?

A collection of 45 short animated lessons, from how rainbows form to how a volcano erupts to how your heart works. KoKo explains each one out loud, and your child can tap Ask KoKo to ask a follow-up question.

Can I see what my child watched?

Yes. KoKo Weekly lists the lessons your child watched and the Fun Facts they read, along with their Discoveries. It is all kept on your phone, behind your PIN.

Every "why?" deserves a kind answer.

Download KoKo and give your child a safe place to wonder.
