Give your children safe access to digital video content through a by you defined trust domain for your child.
Kubo uses filters that adapts to your family's values and community connections. This is done with revolutionary technology which uses TEPP and Web of Trust filters.
Build on human trust
Build your child's content world from the inside out - starting with your inner-circle, expand to friends of friends and extend it with communities.
What is Kubo?
Kubo is a minimal, child-safe video consumption platform built to demonstrate the Trust Extended Permissions Protocol (TEPP) protocol in a real-world application.
Our goal is to demonstrate how TEPP can be used as a parent to create and grow a trust domain with your child.
The platform serves as both a practical tool for families and a reference implementation for developers looking to build on the TEPP protocol.
The problem
YouTube Kids is broken.
Algorithmic control
Algorithms deciding what your child sees, not you
Unknown creators
Content from creators you've never heard of or vetted
AI slop flood
YouTube is getting flooded with AI generated content.
Filter failures
Age-inappropriate content slipping through automated filters
One-size-fits-all
Generic filtering that ignores your family's unique values and preferences
No parental agency
Little control over content quality and appropriateness for your specific child
Privacy risks
Multiple rapports show that your children's privacy is not very well respected.

Two apps, one safe experience
Kubo provides separate, purpose-built applications for parents and children
Parent app
Full control and management capabilities for setting up and maintaining your child's safe content environment
Child app
Simple, safe, and fun interface designed for children to enjoy curated content without distractions
Three Levels of Trust
In Kubo, we've defined three distinct trust levels that can be applied to any trust domain, giving parents granular control over content access and interaction.
View-Only
The most restrictive level where children can only view content without any interaction capabilities.
Watch curated videos
No comments or likes
No sharing capabilities
Cannot add new content
Interact
Moderate access allowing children to engage with content through safe interaction features.
All View-Only features
Like and react to content
Safe, moderated comments
Cannot extend trust domain
Extend
Full access level allowing children to contribute to and expand the trust domain.
All Interact features
Suggest new content
Recommend trusted sources
Grow trust network
Trust Domain Per Child
As a parent, you can set and grow a trust domain per child over time. What can be part of this trust domain?
Profiles from People
Family members, friends, and trusted content creators who can contribute to your child's content experience
Relays as Locations
Trusted Nostr relays and content sources that provide safe, verified content for your network
Content as Nostr Events
Individual pieces of content stored as Nostr events, each with its own trust level and approval status
For each item in the trust domain, you can set an individual trust level.
