The US government announced it will replace AI (artificial intelligence) with SI (superintelligence) in all its official documents, and the CEOs of top US tech companies backed the decision by the current US president.Â
Whether we like it or not, and keeping politics aside, there is an increased demand for the .SI domain; those who want to stay ahead of the rest of the AI crowd are already booking their .si domains.
The Brutal Reality of .AI Domains
For years, .ai was the ultimate status symbol for tech startups. But the extension has become a victim of its own success.
- The prices are absurd: Registering a .ai domain costs between $70 and $150 every single year.
- The good names are gone: Try finding a short, one-word .ai domain today. They are all taken.
- Aftermarket greed: Domain squatters are selling basic .ai names for tens of thousands of dollars.
If you are a massive corporation, you can afford this. But if you are a bootstrapped founder or a smart startup, paying these prices just for a domain extension makes zero business sense.
Why .SI is the New Global Gold Rush
The .si extension is exploding in popularity strictly because of the Super Intelligence narrative. Tech companies want to brand themselves as “SI” companies, and .si is the perfect, clean way to do it.
Here is why you need to look at .si right now:
- It perfectly matches the trend: “Super Intelligence” is the new standard. .si is the exact acronym for it.
- It is highly affordable: A .si domain costs a fraction of what .ai costs. You get a premium tech feel without the premium tax.
- Premium names are still available: Because the mainstream crowd is still stuck on .ai, you can actually find short, clean, and highly brandable .si names today.
- Easy global registration: You do not need to live in Slovenia to buy one. Anyone in the world can register it.
- HostWP.io registers them easily: You do not need to hunt for shady registrars. HostWP.io provides fast, secure, and direct .si domain registrations so you can secure your brand instantly.
Head-to-Head: .AI vs .SI
Let us break down the actual differences in plain English.
- The Hype Factor: .si is the new, trending standard driven by the Super Intelligence movement.
- Pricing: .ai will drain your budget. .si is cheap and standard.
- Availability: .ai is sold out. .si still has great inventory.
- Brand Perception: .ai looks like everyone else. .si makes you look like an early adopter who understands where the industry is heading.

| What matters | .AI | .SI |
| What most people read it as | Artificial Intelligence | “Super Intelligence” as a new brand idea |
| New registration | US $85.60 per year; two years required, so US $171.20 upfront | US $29.99 for one year |
| Renewal | US $85.60 per year; two years required | US $29.99 per year |
| Name choices | Popular short names may be taken or cost extra | You may find more open names, but check first |
| Brand feel | Clear and well known in tech | New, playful, and less familiar |
| Google search treatment | Google treats .ai like a general domain | Google doesn’t list .si among the country-code endings it treats as general |
Who Should Choose Which?
Stick with .AI if:
- You have a massive venture capital budget.
- You are building an enterprise tool and need instant, traditional recognition.
- You do not mind paying $100+ every year just for a domain name. The pricing for .ai domains fluctuates massively.
Go with .SI if:
- You want to ride the “Super Intelligence” branding wave.
- You want a short, memorable domain without paying squatter prices.
- You are a smart founder who wants to get in early before the rest of the market realizes what is happening.
- You want to save money and invest it in your actual product instead of a domain extension.
The Risks You Must Know
Every trend has its risks. Keep these things in mind before you buy.
- The trend could shift: If the world stops using the term “Super Intelligence” in a few years, the .si hype will cool down, and it will just go back to being a standard domain.
- Typo mistakes: People are so used to typing .com that they might mistype your URL at first. You will need to market your domain clearly.
- Educating your audience: Some people might not yet know what “SI” stands for. You will have to tell them it means Super Intelligence.
Author’s Take
Here is my honest take on this. The shift from Artificial Intelligence to Super Intelligence is not just a political talking point; it is a massive branding shift. And in business, he who controls the branding controls the market.
.si is currently the smartest domain hack available. While everyone else is fighting and overpaying for .ai domains, you can quietly register a perfect .si domain for cheap. Yes, it is technically Slovenia’s country code, but the tech world only sees “Super Intelligence”.
If you believe this new terminology is here to stay, grabbing a .si domain right now is a no-brainer. You get a premium, tech-focused brand name before the masses catch on and drive the prices up.
Final Words
The “Super Intelligence” era is here, and the domain market is reacting fast. .si is currently the best-kept secret for tech founders who want a clean, affordable, and highly relevant domain name.
Do not wait until the trend becomes mainstream and the good names are gone. Secure your .si domain today through HostWP.io. And once you have your new domain, make sure you host it on HostWP.io’s high-speed servers to give your Super Intelligence project the fast, reliable foundation it needs to succeed.
