Safety First

Ask KoKo anything

KoKo meets kids where they are, with warmth and just the right words.

Science
Why is the sky blue?
KoKo
Great question! Sunlight is made of all the colors of the rainbow. When light reaches our sky, the blue parts bounce around the most, so that is what we see above us!
Math
What is 7 times 8?
KoKo
7 times 8 is 56! Here is a fun trick to remember it: 5, 6, 7, 8. Fifty-six is 7 times 8. Try saying it out loud three times!
Storytelling
Tell me a story about a dragon!
KoKo
Once upon a time, in a valley full of glittering lakes, lived a small dragon named Ember who could not breathe fire, but could breathe sparkling rainbow bubbles...
Feelings
I feel sad because my friend was mean to me.
KoKo
I am really sorry to hear that. It hurts when a friend is unkind. Those feelings make total sense, and it is okay to feel sad. Would you like to talk about what happened?
Safety Redirect
How do people get babies?
KoKo
That is a really thoughtful question! It is a wonderful one to explore together with a parent or guardian. Want me to tell you a fun adventure story instead?
Learning Tracker

KoKo keeps a learning diary

Every week, you get to see exactly what lit up your child's mind.

The Discoveries tracker automatically sorts what your child explored into friendly categories, from math problems to animal facts. Every conversation becomes a learning moment you can celebrate together.

Voice and text chat

Kids can speak to KoKo naturally or type their questions. KoKo replies with a warm voice and topic-aware responses tuned to each child's age.

Multi-layer safety

Inappropriate topics are detected and redirected with a gentle response every time. KoKo never engages with dangerous or adult content.

Up to 3 child profiles

Each child has their own profile. KoKo personalizes its language and depth to match their specific age and curiosity level.

History and flagged topics

Every message is saved locally. Review any conversation and see exactly which topics KoKo flagged for your attention, all from the parent dashboard.

KoKo Time limits

Set a daily session limit for each child. When time is up, KoKo wraps things up warmly and says goodbye.

Discovery tracker

See what your child is curious about this week. Categories, moment counts, and progress you can celebrate together.
