The vocabulary moved
Artificial intelligence is now a commodity phrase on every pitch deck. The frontier talks about something else: superintelligence. Some of the best-funded labs in the world already carry the word in their names.

.ai was the warm‑up.
.si is what comes next.
The .ai precedent
.ai is the country code of Anguilla. It became the default address of an entire industry simply because it spelled the right two letters. .io did the same for developers. When a country code reads as a word, the market follows.
Early is everything
.si is the official extension of Slovenia, a stable EU registry. The short, pronounceable names are a finite pool, and they go first. The people who bought good .ai names early did not regret it.

Length3 letters+ .si
Reads asJyx SIJyx SuperIntelligence
J, Y, X. Three of the least used letters in English, arranged into a single punchy syllable. Jyx has the snap of jinx and the speed of lynx without carrying either. It is pure brand: short, sharp, and impossible to confuse with anything else.
One syllable
The shortest spoken name possible. It works as a verb (just jyx it), a product and a company at the same time.
Typographic gold
A descender, an ascender and a crossing stroke. Designers can build a whole identity from these three shapes.
Nothing like it
No dictionary meaning to fight, no famous brand next door. You define what Jyx means, and nobody can take that away.
