Spend on the child, not another machine.
Reusing a capable old computer can lower the cost of a dedicated creative place. Greia's small-memory reference helps keep the core lean.
A COMPLETE LINUX OS FOR CHILDREN
Their whole
computer.
Their world.
Install Greia and the machine boots into a creative, child-friendly world instead of a normal desktop. Children make and explore. Parents stay in control.

Turn an old netbook
into their own computer.
Download the installer, write it to a USB stick and install Greia on a netbook or PC. Step-by-step help for Windows, macOS and Linux is on the download page.
01 / WHAT GREIA IS
It changes
the whole computer.
Greia is a Linux distribution, not a children's app sitting on top of somebody else's desktop. Installation gives the device a Greia boot, child profiles, Greia Shell and Activities. The usual Linux desktop, terminal, file manager and browser are not the child's route through the machine.
01Turn it on
→A continuous Greia arrival leads to a choice of child profile.
02Enter Greia
→Large Collections lead to making, playing, learning and exploring.
03Always find Home
Activities have their own worlds; Greia keeps the protected way back.
Linux is the foundation. Greia owns the child's visible experience and the shared rules for identity, storage, input, permissions, package trust and parent control.
Explore the four layers ↘02 / A LOOK INSIDE
Real screens.
Real possibilities.
These are current English-interface captures from the real-service development Simulator, not illustrations of an imagined product. Browse the Shell and a selection of Activities, then enlarge a frame to see its details.
THE CHILD SHELL
A starting place of their own.
Simulator captures show the development source at the stated date. They do not certify a public installer or every physical device.
03 / MORE USE FROM MORE COMPUTERS
Give hardware
another childhood.
Greia is being built for all kinds of practical computers, from first-generation netbooks onward. Old machines matter because a useful child computer need not begin with a new purchase. Raspberry Pi 400 and 500 are equally important: add a display and hand your child the computer inside the keyboard.
ONE GREIA EXPERIENCE · MANY POSSIBLE MACHINES
MAKE GOOD HARDWARE USEFUL AGAIN
From netbooks onward.
Greia aims to make older laptops and small PCs useful, legible and pleasant for children. The first-generation Acer Aspire One is our toughest low-resource reference, not the only computer we care about.

Device by devicecompatibility verified
Hardware support is a goal verified per device and image; the current site does not promise that every PC is ready today.
The computer in the keyboard.
With a Pi 400 or Pi 500, a parent can connect a screen, then give their child a compact computer built into the keyboard itself.
One Greia across devices.
The Shell, Activities, parent rules and portable child data are designed to travel across old x86, ARM and other supported hardware.
04 / WHY THE SYSTEM CAN GROW
One world.
Many possibilities.
Greia is a complete operating environment with clear owners. The child sees the Shell and Activities. Underneath, Greia keeps the rules that make different machines and different Activity authors feel like one dependable place.
01 / THE CHILD'S WORLD
A place they can learn by using.
Each child explicitly chooses a Greia profile. The Shell presents Activities in understandable Collections, and Greia keeps a real Home control available above an Activity.
Learn a move once.
Activities share keyboard, pointer, touch and controller meanings. A child should not have to relearn basic controls every time they enter a new world.
Openness with rules.
Packages declare their needs. Greia checks them before installation, keeps saves in each child's profile and retains the protected route Home.
Their work belongs to them.
Writing and Painting are first-party creative starting points. Profile-scoped storage and portable logical backups are part of the platform contract.
05 / CONNECT FOR THE GROWN-UPS
Their space.
Your decisions.
Greia works without an Internet connection for core child use. A local network makes it more useful: parents can open Greia Parents on their own phone or computer to manage the child's machine. Network access does not turn the child experience into a general web browser.
ONE CHILD AT A TIME
A real place for each child.
A child picks their profile at boot. Writing, drawings, Activity saves, progress and language preferences belong to that profile.
- Separate creations and Activity data.
- Age suitability and challenge are different choices.
- Parents choose which Activities this child sees.
The image is one real development client viewport, opens as a single original 1024×600 capture. It displays “This Greia”; the topic buttons explain other Parent capabilities.
The network is for parents.
Put Greia on your home or school network so a parent can manage it from another device. Core play and saves remain available offline.
A child-safe route.
Normal child use has no general browser, search bar, desktop or arbitrary web escape. Activity network access is denied by default and must be explicitly mediated.
Manage the actual device.
Parent controls cover profiles, visibility, supported hardware settings and connected parent devices through Greia-owned services.
Parent pairing uses device-owned HTTPS on the local network; installed browser and certificate acceptance are still being completed. The site describes the intended family experience and the development client honestly.
06 / ACTIVITIES MADE FOR ONE CHILD
Tell an agent
what they love.
Greia's Activity SDK gives coding agents explicit rules and tools for making Activities. Today a contributor can give those tools to Claude or ChatGPT and ask for something shaped around a child. The planned family Creation Pack will let parents install the kit on their own computer, describe an idea and receive a tested package to approve for their child's Greia. That guided family route is still in development.

Then choose the kind of play
ONE POSSIBLE ACTIVITY
Our little garden
Plant a seed, draw what grows and come back to notice the change.
THE GREIA ACTIVITY KIT · AGENT-READABLEFrom a request
From a request
to a real Activity.
- Ask for something personal.Tell Claude, ChatGPT or another coding agent what the child enjoys, what they are practising and how they like to play.
- The agent reads Greia's rules.The public authoring skill covers pre-reader design, input, storage, Home, package structure, performance and validation.
- Build, listen and test.The agent creates a coherent play loop, produces reviewed prerecorded voice cues through Greia's voice engine and checks it in the real-service Simulator.
- Parent approval comes last.After package validation, the parent receives a
.greiaactivityfile. Greia checks it, and the parent chooses whether to install and show it to a child.
The contributor SDK and bounded new-install service exist today. Installing the polished family Creation Pack on a parent's computer, and the ordinary-family package installation lifecycle, remain work in progress.
Read the Activity authoring skill ↗07 / BEFORE THEY CAN READ
A world they
can hear.
For a young child, speech can carry a welcome, a hint or the sound of a new word. Greia designs for children who cannot yet read: clear pictures and controls do the first work, while short, repeatable voices help them understand and feel accompanied.
“Hi! I'm Lilli! I love making up stories, drawing colorful things, and finding a little magic everywhere. Got a silly idea? Come with me!”
Designed into the Activity. Authors identify the exact moments that need speech: a first demonstration, a hint, a phoneme, a celebration. Audio is not a patch for a confusing screen.
Generated while creating, not while playing. Greia's voice-production engine can make the localized recordings as part of an agent's authoring work. People review them, then the child computer plays small files with no live voice model.
08 / A WORLD IN MORE THAN ONE LANGUAGE
Same place.
Another language.
Language is a Greia profile and content concern, not a different product. Here is the same Encyclopedia home screen captured in English and Italian. Selectable language does not automatically mean every Activity and voice is fully translated or certified for release.
09 / OPEN SOURCE, OPEN POSSIBILITIES
More children.
More chances.
Greia is being built as an open-source educational platform. Reused machines, low-cost hardware and independently created Activities could help families, schools and community programmes, including those in lower-income countries, offer creative computing without buying a fleet of new PCs or tying every child to an online service.
Learning that can be made locally.
Teachers and schools could curate their own Activity collections and create lessons tailored to language, curriculum and community.
A smaller hardware bill.
Old netbooks and compact computers can be practical dedicated child machines. This may matter especially where new devices and reliable connectivity are expensive.
Build on what exists.
The OS and Activity contracts aim to be open to families, educators, developers and agents. Independent distribution stays possible alongside a future curated catalogue.

11 / THE PRACTICAL QUESTIONS
Good questions.
Clear answers.
Greia is a real operating-system project in development, not yet an ordinary-family release. Here are the distinctions a parent should be able to see immediately.
Is Greia an app or a whole operating system?＋
A whole child-focused Linux distribution. Installation gives the computer a Greia boot, profile picker, Shell and Activities. A conventional desktop is not presented during normal child use.
Does the child need Internet access?＋
No for core play, saves and built-in Activities. A local network is useful for Greia Parents on a phone or another computer. Normal child use does not include a general web browser; an Activity's network permission is denied by default and must be mediated.
Which computers can run it?＋
Greia targets a broad hardware range: early netbooks, other PCs and Raspberry Pi 400/500 among them. Support is verified per device and release image. Download pages will name the tested scope rather than imply that every machine is already certified.
Can children make things, not only play games?＋
Yes. Writing and Painting are mandatory first-party creative Activities for the first user-ready image, with profile-scoped autosave and child-sized controls. Their final release and hardware acceptance still need their named gates.
Can I ask an AI agent to build an Activity?＋
The Activity authoring skill is designed for coding agents as well as people. A parent can describe an idea, and an agent can read the public rules, create and validate an Activity, produce prerecorded voice and test it. The polished family self-service path is still being developed; package installation always remains parent-authorized.
How will individual Activity downloads work?＋
The planned parent-facing package is a .greiaactivity file. The Activity library is ready to list individual packages as they are reviewed and published. There are no public packages to download from this work-in-progress site yet.
Do the voices require AI on the child computer?＋
No. Voice generation happens during authoring. Short lines are reviewed and stored as audio, so the low-resource child computer only plays them back. Meaningful visual cues remain important as well.
Is the code public and is the installer ready?＋
A technical-preview installer for netbooks and PCs is on the Downloads page, with instructions for writing it to a USB stick and installing it. It is meant for people comfortable trying new software, not yet a family release. Greia is built for an open-source ecosystem; public-repository preparation is ongoing.
