Language Evolution Simulator

This isn't a product. It's a hyper-specific academic simulation tool that probably only matters to you and maybe 46 other people on Earth. But if you're one of them, congratulations on your extremely niche interests.

> Real-time language evolution with distinctive features
> Procedural world generation using cellular automata
> 33 phonemes, 300+ vocabulary items, actual linguistics
> Geographic spread, borrowing, splitting, and mutation
> Multiple visualization modes and interactive inspection
> Configurable parameters for reproducible chaos
Launch Simulator

No signup, no tracking, no business model. This is a passion project that escaped into the wild.

Built by someone who thought "you know what's missing from the internet? A fully-featured language evolution simulator with cellular automata world generation." The internet disagreed. It was not missing. Here we are anyway.

There is no business here. This isn't a startup pivot waiting to happen. It's just a thing that exists because someone thought it should exist.

Why does this exist?
Academic curiosity met programming skills at 2am. This is what happens when you can't find the tool you want, so you spend 200+ hours building it yourself instead of doing literally anything else productive with your life.
Why is it free?
It runs entirely in your browser using your machine's resources. No servers, no hosting costs, no data collection. Also, the addressable market is approximately 47 people. Stripe won't even approve an account for that.
Is the linguistics actually real?
Yes. It uses distinctive feature theory, phonotactic constraints, and models actual sound change patterns from historical linguistics. The nerdery is authentic.
Who maintains this?
One person with too much free time and an unreasonable attention to phonological detail. Contributions welcome but not expected. This is hobby-grade infrastructure.
Linguists & Researchers
If you've ever wanted to test theories about language contact without waiting 500 years for real data, this is for you. It's not peer-reviewed, but neither is your Twitter thread about sound changes, so here we are.
Conlang Enthusiasts
You're already past the point where normal people understand your hobby. Generate naturalistic sound systems and watch dialect continua form in real-time. This is your people.
Worldbuilders & Writers
Your fictional world needs language maps that make geographic sense, and you're detail-oriented enough to care. Exactly zero of your readers will notice. You will notice. This is your curse and your calling.
The Inexplicably Curious
You saw "cellular automata" and "phonological drift" and thought "I need this immediately" despite having no practical use for it. That's valid. Welcome home.
