The kids' corner
Learning games for ages 3+ — pictures, spoken instructions, no ads and no losing screen.
KidsActiveTiny World
Colours, shapes, counting, letters, blending and adding in one game that finds your child's level by itself — harder after three right answers, easier and hinted after two wrong. Every four right answers add a house, a tree or an animal to the little world they keep.
Let them playKidsActiveTiny Band
Five colour tiles where every tap sounds right, echo games with the owl, and real songs played phrase by phrase. Five instruments synthesised on the device, a flute you blow into, and a colour strip to play on a toy xylophone.
Let them playKidsActiveLittle Puzzle
A jigsaw of your own family photo, cut on the device and never uploaded, or one of ten ready-made pictures. Four to twelve pieces; a wrong piece wobbles back, and the owl says where it goes in the words school uses. Print the picture as a six-piece sheet to cut out.

Open boardMission
Technology should serve everyone
We believe useful tools should not be limited by paywalls or intrusive advertising.
YouUseAI started with a simple question: why do the most useful apps often come with ads, paywalls, or complicated sign-up flows?
We build every app to be simple, fast, free, and respectful of users. No investors to please, no revenue pressure — just a passion for building something genuinely useful.
What you get
The parts that work everywhere
Not one product — the things that hold true across every game, tool and board on the site.
Progress that follows you
Sign in with Google and your stars, scores and unlocks sync between devices. Two machines merge on the higher record, so nothing you earned is ever lowered.
Your data, visible and removable
Your profile lists everything the site has stored about you. Take a copy, or delete all of it, in one press — and nothing here needs an account in the first place.
Everything you make is shareable
A birthday card, a route plan, a timetable — each one becomes a link you can send. Whoever opens it needs no account either.
Your work comes with you
Every tool lets you copy the result, download it as a file, or open that file again later to carry on. Nothing you make is locked inside the site.
Two languages, two themes
Every screen is written in both English and Vietnamese and drawn for both light and dark. Switch either one whenever you like.
It runs on your machine
Games and tools compute in your browser, not on a server. Once a page has loaded, most of it keeps working with the network gone.
FAQ
Frequently asked questions
What people often ask about YouUseAI and how we work.
Is YouUseAI really free?
Yes — every game, tool and download, with no premium tier, no ads and no paid features. There is nothing here to buy.
Do I need an account?
No. Everything works signed out. Signing in with Google adds exactly one thing: your progress syncs between devices instead of living on a single machine.
What happens to my data?
Games and tools run in your browser, so what you make stays there. If you do sign in, the site stores your email address and your game progress — nothing else. Your profile page lists all of it and deletes it on request.
Does it work without a connection?
Mostly. Games and tools compute on your machine, so once a page has loaded it keeps working offline. Only the boards that read live data — gold prices, route lookups — need the network.
Is the source code open?
It is published so that anyone can read exactly what the site does with their data, but it is not licensed for reuse. Reading it and reporting problems in it are welcome; copying or redistributing it is not.
How do I report a bug or ask for something?
Use the feedback board on this site. Every request is read, and the ones people vote for are the ones built first.
