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.

How it works

1

Take a challenge

The AI Workshop sets a mission: design a pet, a race car, a sweet shop, an airplane.

2

Describe it in words

Vague ideas come out hilariously wonky — on purpose. “A dog” gets you a sad grey blob.

3

Sharpen the idea

Friendly hints show what’s missing. Add the details, and the real thing appears — then it follows you, drives, or flies.

4

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.

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.
