Element 119. The one not yet made.

The periodic table ends at 118. Our symbol is Ch 119 — the first element nobody has made — with the frame opening where the AI stars break out. The name comes from the Greek chrysos, gold, and ergon, work. Say it chry-SER-gia, with the stress on “ser”.

What we believe

Three principles we don't trade.

Your knowledge is yours

A system that grows as you use it must never be switched off by its vendor. That's why we sell a perpetual right to use, never a subscription.

No vendor at the centre

Chrysergia serves every AI equally. If any vendor — including us — disappeared tomorrow, your system would still work.

Claims with evidence

We say "combination", not "first". We publish what the field already does, and where others are better.
