-
Evolution Tank
Slug-like creatures with tiny neural-network brains learn to find food, outrun predators and evolve into new species, live, as you watch.
-
Haunted Autocomplete
A text box with predictive text that starts out helpful, then slowly gets possessed. The more of its words you accept, the stranger it gets.

What is Neuralized.si?
Neuralized.si is a small online lab of AI experiments built to be played with rather than read about. Each experiment is a single web page that shows one idea from artificial intelligence, like neural networks, evolution or text prediction, doing something you can see and mess with.
They’re meant to be a little odd. A tank of creatures inventing their own survival tactics, or a predictive keyboard that’s clearly hiding something, sticks in your head longer than a diagram does.
How the experiments work
- Everything runs in your browser. There is no AI service behind the page, no account and no server doing the thinking. Your typing in Haunted Autocomplete never leaves your device.
- The AI is real, just small. Evolution Tank uses actual neural networks and genetic evolution. Haunted Autocomplete uses a Markov chain, the same next-word idea behind your phone keyboard.
- Each page explains itself. Below every experiment there’s a plain-English write-up of what’s happening and things to try.
Questions
Are the experiments free?
Yes. Every experiment is free to use, with no sign-up and nothing to download. They work on desktop and phone browsers.
Do the experiments use ChatGPT or another AI service?
No. Each one runs its own small AI right in the page, so it works without an AI service and nothing you do is sent anywhere.
Which experiment should I try first?
Start with Evolution Tank if you like watching things unfold, or Haunted Autocomplete if you’d rather play. Both take about a minute to get interesting.
Will there be more experiments?
Yes. New experiments are added to the table as they’re discovered. Each gets its own number, like 001 and 002.
