Built for AI.
Ready for SI.
Thirteen short, brandable domains across the two extensions that define intelligence technology: the established .ai and the fast-rising .si. Led by the 3-letter ziq.ai and offered together as a single portfolio.
The names
Short, pronounceable and free of dictionary-word collisions. Each one is ready to become a product, a company or a model name.
.ai · The proven home of AI companies worldwide
.si · The emerging extension for super intelligence
A portfolio that can't be assembled twice
Great domains are usually bought one at a time, from different owners, over years. This set is available in one transaction.
Fixed supply
Every domain exists exactly once. There are only 17,576 possible three-letter .ai names in total, and the short, pronounceable ones are long gone from open registration. ziq.ai is one of them.
Closing windows
Short .si names that read well in English were claimed within weeks of the SI announcement. Names of this quality now trade almost entirely on the aftermarket, one seller at a time.
One owner, one transfer
Buying piecemeal means negotiating with many holders, at rising prices, with no guarantee of completing the set. Here all 13 names come from one owner through a single escrow.
Once this portfolio is sold, it will not be offered again in this form.
Two extensions, one strategy
.ai is where the industry builds today. .si is where its new vocabulary is heading. This portfolio holds strong names in both.
.ai, the established standard
About 1.5 million .ai names are registered, and the extension has become the default address for AI companies. Short .ai names have sold for six and seven figures.
.si, the next term
A September 29, 2026 US executive order adopted "Super Intelligence" and "SI" for official use. The .si registry added more than 46,000 names that month, up from about 3,500.
Coverage for a brand or a fund
A company can launch on .ai and hold the matching .si direction. An investor gets diversified exposure to both extensions in a single acquisition.
