Super Intelligence or Superior Intelligence? Both names point to the same initials: SI. For anyone building an AI product, research project or automation service, that offers an interesting way to think about a short .si domain name.
On September 21, 2026, the official White House account on X shared a poll quoting President Donald J. Trump:
“Which name do we like for the new phenomena — SUPER INTELLIGENCE VS. SUPERIOR INTELLIGENCE?”
The final result was close: Super Intelligence received 50.5% and Superior Intelligence received 49.5%, with 58,642 votes cast. View the original White House poll.
For a founder choosing a name, SI can suggest super intelligence, superior intelligence or simply the initials of a distinctive brand. Pair a memorable name with .si and you have a compact address for an AI tool, a software company, a research publication or a new online service.
The connection is a branding idea: .si is Slovenia’s country-code domain, managed by Register.si at ARNES. The poll concerns terminology; it does not announce a domain policy or endorse .si registrations.
Our new .si page brings together domain search, current registration and renewal prices, available-name suggestions and practical registration guidance. Start with your project’s name, explore alternatives and check which address fits.
