The city built with words
Tomospire is a voxel world with a twist: the coolest things aren’t crafted with taps — they’re described. A pet. A race car. A plane. A whole shop. The clearer the idea, the better the result — precise thinking and fluent AI collaboration, picked up through play.

Live from the city
Real worlds and real ideas, straight from the game — right now.

How it works
Take a challenge
The AI Workshop sets a mission: design a pet, a race car, a sweet shop, an airplane.
Describe it in words
Vague ideas come out hilariously wonky — on purpose. “A dog” gets you a sad grey blob.
Sharpen the idea
Friendly hints show what’s missing. Add the details, and the real thing appears — then it follows you, drives, or flies.
Earn real powers
Planes, bulldozers, paint shops and more unlock only by completing challenges. Thinking is the power-up.
Skills that stick
It never feels like a lesson — but every unlock exercises an ability that lasts.
Clear thinking
Turning a fuzzy wish into a precise description is the core skill behind writing, engineering and design.
AI literacy
Describe, check the result, refine, try again — exactly how people will work with AI for decades to come.
Creative persistence
First tries fail funny, not frustrating — and refining an idea beats giving up on it.
For parents
Not another tapping game. Tomospire rewards exactly one thing — putting an idea into clear words — and that skill spills over into homework, stories and everyday conversation.
Screen time that gives back
Every unlock is earned by describing something precisely. There’s nothing to watch passively — the game simply doesn’t respond to it.
Practice for an AI world
Your child will grow up working with AI. Here they build the healthy habit early: say clearly what you want, check the result, refine it — always with them in charge.
Private by structure
No account, no profile, no personal data. Worlds are invite-only, there are no ads or trackers, and progress lives under a simple code you can stick on the fridge.
How to use it at home
- Play the first challenge together — describing things out loud is half the fun.
- Ask for a tour afterwards: “What did you write to get that plane?” The answer is the learning.
- Write the save code down together — that little code is the whole “account”.
For schools & teachers
A descriptive-writing and AI-literacy exercise disguised as the game your class already wants to play — and it runs on whatever hardware the classroom has.
Zero setup
Opens in the browser on any Chromebook, tablet or laptop. No installs, no licences to manage, no student sign-ups.
No student data
There are no accounts, so there’s nothing to collect — no names, no emails, no profiles. The paperwork stays as simple as the login.
Fits your curriculum
Descriptive writing and vocabulary in language classes; prompt design and AI literacy in computing; iteration and feedback in design lessons.
A ready-made lesson shape
- Create a class world and put its room code on the board — only your students can enter.
- Set one challenge for everyone: “design a race car that actually drives”.
- Compare first attempts — wonky results show exactly which details were missing.
- Close by reading the best descriptions aloud. That’s the lesson, in their own words.

Designed with care
The best design choices are the quiet ones. A few of ours:
No accounts
Play starts instantly. Worlds and progress live under simple random codes — no sign-ups, no profiles, no personal data involved.
Invite-only worlds
There’s no public server list. A shared world is a small space others enter only with its code.
Builds stay as built
Only a build’s creator — or the world’s owner — can change it, so creations stay the way they were made.
Looked after
Every world can be reviewed, restored to an earlier moment, or closed by the operators when something’s off.
Quiet by design
No third-party ads, no analytics trackers, nothing sold to anyone.
FAQ
How much does it cost?
It’s free during the alpha. An optional plan with extras may come later — never ads, never loot boxes.
What does it run on?
Any modern browser — phone, tablet or laptop. You can add it to the home screen like an app; there’s nothing to install.
Is this Minecraft?
No — it’s an original browser game. It shares the friendly blocky look, but the heart of it, building with words, is all its own.
How do friends join?
With a short room code. Only people who have the code can enter, and each world stays a small group.
