For the last several years, .AI has been the domain extension associated with the artificial intelligence boom. It has become the default choice for AI startups, product launches, research labs, and technology companies looking for a memorable alternative to increasingly crowded .com space.
Now, another two-letter extension is attracting increasing attention: .SI.
While .si is the country-code top-level domain (ccTLD) for Slovenia, a recent surge of interest has transformed it into the latest topic in domain strategy conversations. The catalyst wasn’t a technical breakthrough or the Slovenian registry breaking through with an impactful marketing campaign. It was politics.
Following recent U.S. government efforts to champion the term “super intelligence” (SI) over “artificial intelligence” (AI), registrations under .si have reportedly surged dramatically, creating new opportunities, and new risks, for brands operating in the AI sector.
For Canadian businesses, startups, and brand owners, the real question isn’t whether .si will replace .ai. It’s whether the sudden attention creates a strategic reason to secure your brand before someone else does.
Why .SI Is Suddenly Trending
In September 2026, President Donald Trump publicly argued that the term “artificial intelligence” was misleading because the word “artificial” implies something fake. Trump called for the technology to instead be referred to as “super intelligence” or “SI”, later formalizing that preference through an executive order directing federal agencies to adopt the terminology in public-facing communications.
Whether the terminology ultimately gains broad adoption is beside the point. The rebranding of AI to “super intelligence” by the US President triggered an unprecedented surge in .SI domain registrations. According to Slovenia’s national registry, registrations of .SI reportedly jumped from fewer than 2,000 monthly registrations in August to roughly 44,000 in September, an increase of more than 2,100%.
Like many domain trends before it, the bulk of the registration rush was driven not by market demand but by the belief that future demand might emerge. While proactive and defensive .SI domain registrations by brands and businesses were certainly part of the surge, domain investors and speculators no doubt comprised the majority registrations.
For brand owners, however, this distinction is important because domain registration spikes often create scarcity long before real-world adoption catches up.
AI and SI Are Not the Same Thing
Before looking more closely at domain strategy, let’s clarify the terminology.
Artificial intelligence refers to today’s generation of systems capable of performing specific tasks such as language generation, image creation, pattern recognition, software coding, and decision support. AI is real, practical, and already deeply embedded into modern business operations.
Super intelligence, by contrast, generally refers to a hypothetical future state in which machine intelligence exceeds human cognitive abilities across virtually every domain. It is often discussed alongside concepts such as AGI (Artificial General Intelligence), frontier models, autonomous systems, and recursive self-improvement.
The main takeaway is that AI exists today and is rapidly evolving while super intelligence remains largely theoretical.
The terms, when used correctly, are not interchangeable.
From a branding perspective – not to mention that of the U.S. President – “SI” has obvious appeal. It sounds futuristic, ambitious, and a little bombastic. It also abbreviates down to two naturally memorable letters, creating brand able alignment between a technology concept and an existing domain extension.
And this is where domain strategy enters the discussion.
What Are .AI and .SI Domains?
Although they are increasingly being used as technology branding tools, both extensions are technically country-code domains or ccTLD’s, just like the .CA domain name for Canada.
| .AI Country Code Domain Name | .SI Country Code Domain Name |
| Country-code domain for Anguilla Widely adopted by AI companies globally Treated by Google as a generic TLD rather than a geographic indicator More than 1.4 million domains registered Typically requires a minimum two-year registration term Registration costs are significantly higher than many other extensions Two year registration term is required | Country-code domain for Slovenia Open to registrants worldwide No local presence requirement Registration terms are generally more flexible Significantly lower registration costs Recent registrations have surged due to “super intelligence” branding interest Can be registered for a one year term |
Geographic Relevance VS. “Super Intelligence” Rebranding
For registrants wishing to use their .SI domain name for an online presence, it’s important to keep in mind that .SI remains Slovenia’s national domain.
Unlike .AI, Google currently does not classify .SI among the ccTLDs it treats as generic for global search targeting.
Businesses considering .SI as a primary website address should understand the search implications before planning any major migration or new website project.
A Domain Rush Is Not a Reason to Rebrand, But to Consider Defensive Registration
Whenever a domain extension becomes associated with a major trend, it’s important to remember that a spike in registrations measures just that – registrations. It does not measure or reflect consumer recognition, market trust, brand memorability, or long-term value.
If your company already operates successfully on .CA, .COM, or .AI domain. name, there is rarely a compelling reason to abandon that address because of a new naming trend.
Your corporate domain strategy should support business goals and a worthwhile domain registration should always have a clear purpose, such as the following examples:
- Primary corporate website
- Product launch
- Research initiative
- Marketing campaign
- Short redirect domain
- Future proofing
- Brand protection and defensive registration
Is .SI Becoming Preferable to .AI?
For AI-focused companies and initiatives, .AI remains the strongest primary branding extension available outside of .COM.
Investors, customers, media, partners, search users and the general public already understand what .AI represents. That market recognition took years to develop and cannot be replicated overnight.
However, asking whether .SI is preferable to .AI mis probably the wrong question right now. A better question might be whether both have a role to play and what that could be.
An up-to-date corporate domain portfolio might look like:
| .CA – yourcompany.ca | For Canadian identity, trust and audience |
| .COM – yourcompany.com | For global corporate operations and branding |
| .AI – yourcompany.ai | For AI-focused products, initiatives, resources |
| .SI – yourcompany.si | For research initiatives, future projects, campaigns, or defensive protection |
As you can see, these domains do not have to compete with one another. They can complement each other and each have their own use case.
Why .SI Presents a Brand Protection Challenge
For most brands, the most compelling argument for registering a .SI domain right now is not branding, but defensive brand protection and future proofing.
When a new domain trend emerges, speculators and cybersquatters alike move quickly. Valuable names are often registered before legitimate businesses have a chance to evaluate their options.
For companies already operating in artificial intelligence, there are several good reasons to consider securing a matching .SI domain, key among them:
- Prevent third-party registrations of your brand, corporate and product names
- Reduce the risk of impersonation and phishing
- Limit opportunities for customer confusion
- Protect future product naming options
- Avoiding expensive recovery efforts down the road
Proactive and preventative registrations matter because recovering a domain after someone else registers it is almost always more difficult and more expensive than registering it yourself. Moreover, country-code domains such as .AI and .SI are generally not covered by domain blocking protections like Global Block that are used to reserve names across large portfolios of generic top-level domains.
Dispute resolution can also be more complex where country code domains are concerned. Proceedings may involve the country’s specific alternative dispute resolution mechanisms and may require trademark arguments that are less straightforward than traditional UDRP proceedings.
Viewed through that lens, a defensive .SI registration can be an inexpensive insurance policy, in addition to providing future opportunities for use if becomes recognized for its generic.
Who Should Consider Registering .SI?
Not every company needs a .AI or a .SI domain name; however, registering these extensions may make sense if:
- You operate in the AI, machine learning, automation, or software sectors
- You have a recognizable brand worth protecting
- You already own a valuable or brand .AI domain
- You are launching advanced AI, AGI, or research-focused initiatives
- You want short, memorable naming opportunities unavailable elsewhere
- You want to prevent others from acquiring a logical extension of your brand
Organizations with no connection to AI, research, technology, Slovenia, or the concept of Super Intelligence can probably ignore the trend entirely.
What Should Canadian Businesses Do?
At Webnames Corporate we work with a lot of leading Canadian organizations and brands. Where these organizations are concerned the defensive domain registration hierarchy remains relatively straightforward:
First, secure your .CA, and if your business operates ion the US or internationally, secure your .COM whenever possible.
If artificial intelligence is central to your products, services, or positioning, secure your .A domain and then evaluate whether .SI has value as either a defensive registration or a future branding asset.
The Bottom Line About the .SI and .AI Domain Registration Rush
The recent surge in .SI registrations is another good example of how quickly domain markets respond to political announcements, technology narratives, and emerging terminology.
Whether “super intelligence” becomes the dominant term remains uncertain.
What is certain is that thousands of organizations are already registering .SI domains, reducing availability and creating new brand protection considerations for businesses operating in the AI sector.
For most companies, .AI still remains the primary extension for AI related initiatives and branding. But for many organizations, particularly those with valuable brands, products, or research initiatives, .SI may be worth evaluating now as a strategic defensive registration before availability disappears.
As always, domain portfolio decisions should be built around business objectives, brand protection, and future flexibility. With .SI emerging as trending domain to watch in the technology and artificial intelligence space, we believe its registration is worth consideration given its approachable price point.
