Companions and worlds
The child picks Luna or Theo as a companion. Every world brings its own characters, its own content and its own questions, from tinkering robots to mythology to detective cases.

Kiluni · App for families
The AI companion for kids aged 8 and up
In Kiluni, kids explore three worlds with Luna or Theo, listen to detective audio plays, learn chess and play. No account, no advertising, parents in charge. We run the language models ourselves, on our own servers in Berlin.
Install for free
Free to use, with daily limits. Store links go live at launch.

What Kiluni does
Kiluni does not start with an empty input line. Children pick a character that guides them through topics, and find stories, games and answers there.
The child picks Luna or Theo as a companion. Every world brings its own characters, its own content and its own questions, from tinkering robots to mythology to detective cases.
Stories emerge in conversation. Answers can be read aloud; the voices come from ElevenLabs via its EU workspace.
Games and tools to make things yourself: mini golf, your own zoo, an AI factory. Along the way, children learn how the technology behind it works.
If you would rather talk than type, just talk. The companion answers by voice on request. The microphone stays locked until you release it.
Children can show a picture and talk about it once the camera has been released. Without that release, the camera stays off.
Permissions, time rules, retention and deletion in one place, protected behind a task for adults.
From the app
Screenshots from the current build. Content and companions keep growing, the principles stay.

The home screen leads into the worlds, here Finders’ Workshop.

Luna and Theo. The child decides who comes along.

Every conversation says that an AI is talking and can be wrong.

Real or AI? Kids learn to spot AI pictures.

Safety principles
Kiluni is built for children, so stricter rules apply than for an ordinary app. These six points are not a statement of intent, they are the default setting.
Your child does not register. There are no child credentials that could be lost or passed on.
You confirm the age during setup. A date of birth is never transferred to our servers.
After 90 days, conversation histories are deleted automatically. Anyone who wants to keep them switches that automation off explicitly.
Microphone, camera and notifications stay off until you release them in the parents area. Each release can be revoked there individually.
Kiluni contains no third-party advertising and no advertising or marketing analytics services. We do not sell data and we do not build advertising profiles.
We operate the language models that answer your child ourselves, on our own servers in Berlin. Conversations are processed there. Only if our servers fail does AKI.IO in Berlin take over; no other AI provider receives conversation content.
Hosting, database and the real-time voice connection stay in the EU. Individual services outside the EU, for notifications and subscription management, are named in the privacy policy for the app.
Privacy policy for the app →Parents area
Setup deliberately runs through an adult. What applies afterwards can be changed at any time in the parents area, which sits behind a task for adults.
What Kiluni is not
The companion is marked in the conversation as an AI, not as a person. It replaces neither friends nor parents.
Kiluni gives no medical, psychological or therapeutic advice. Serious matters belong with adults, not with an app.
Kiluni is not built to hold children as long as possible. There is no endless feed and no pressure to return every day. You set the time rules.
No third-party advertising, no product placement, no sharing of data with ad networks.
We do not build personality or advertising profiles of children. Conversations are processed to answer, not to assess.
How it works
Download Kiluni from the App Store or Google Play. Plan a few minutes together for the setup.
An adult identifies themselves, confirms the child age and decides what is released: microphone, camera, notifications.
The child picks a companion and starts. You can change permissions, time rules and retention at any time in the parents area.
Pricing
Kiluni is free to use, with daily limits for chat, pictures and picture analysis. Kiluni Premium removes these limits: a subscription for 1, 6 or 12 months, only in the Parents area, purchased via the App Store or Google Play.
We never see payment data; the App Store and Google Play handle it.
No advertising. No in-app purchases made by children.
Frequent questions
For kids aged 8 and up. The app is set up by an adult who confirms the age and grants the permissions.
No. Kiluni works without the child registering, without a password and without an email address for the child.
No. There is no third-party advertising and there are no advertising trackers. We do not sell data and do not create advertising profiles.
On our own servers in Berlin. Conversations are processed there. Only if our servers fail does AKI.IO in Berlin take over; no other AI provider receives conversation content. Hosting, database and the real-time voice connection stay in the EU.
No. Kiluni uses its own models and its own moderation on its own infrastructure, tuned for children. In the conversation, the companion is visibly marked as an AI.
By default 90 days, after which they are deleted automatically. That automation can be switched off in the parents area. Deleted histories are fully removed from our servers no later than 14 days afterwards.
The parents area sits behind a task for adults. There you manage the permissions for microphone, camera and notifications, the time rules, the retention of histories and the deletion of the profile.
In the parents area via “Delete profile”. After a 14-day recovery period the data is removed permanently. Alternatively, an email to privacy@hillcrownai.com is enough.
