The AI Domain Extension Battle
For the past few years, the .ai extension (Anguilla's ccTLD) has been the undisputed king of artificial intelligence startup branding. However, as the namespace becomes overcrowded and premium .ai names sell for tens of thousands of dollars, founders are looking for alternatives. Enter .si (Slovenia's ccTLD), which is rapidly being adopted to represent Superintelligence.
Cost and Availability Comparison
- Availability: Finding a short, one-word dictionary .ai domain is nearly impossible today. In contrast, the .si namespace is still relatively fresh, meaning you can secure highly desirable, short domains.
- Registration Cost: A standard .ai domain typically costs $60 to $80 per year and often requires a two-year minimum registration. A .si domain usually costs between $15 and $25 per year with no multi-year minimums.
Branding: Artificial Intelligence vs Superintelligence
While "AI" refers to the current era of generative models, "SI" (Superintelligence) looks toward the future—systems that surpass human cognitive abilities. Using a .si domain signals that your company is building next-generation tech, such as AGI (Artificial General Intelligence), swarm intelligence, or autonomous agents.
