CytherAI builds the part of AI that decides what is allowed to happen.

AI makes answers, numbers and parts that look right. Looking right is not a test. CytherAI builds checks that stand outside the model: the model proposes, the system decides. It is based in Riyadh.

Its lead product is CytherCAD: describe a part, and it turns that description into instructions that build it, restricts invalid geometry during generation, and checks the result afterwards. Its second system is SijilOS, a transactional ledger for the Saudi market that runs on the device and works offline. No deployment is claimed for either.
