How not knowing became a method, and how that method became structure

I never had a technical education, but I could still see where tools in the workplace were falling short. Sometimes I could simplify things, automate parts of the work in Excel, and make processes clearer. Then AI came along, and I started experimenting with it. At first, it felt like the solution....

APE is a deterministic AI-first programming language for unambiguous human-AI collaboration. Built in 6 days using XOX, a method where architecture is locked before execution. Includes a compiler, runtime, decision engine, stdlib, 850 passing tests, and integrations for Claude, OpenAI, and LangChain. 9,000+ downloads on PyPI.

Questions about APE, XOX, or what “no code” means in practice?

I expect some of the claims around APE to raise questions, and that’s fair. So rather than overloading the launch page, I wanted to open a space for discussion here. APE was built through XOX. XOX did not come from theory. It came from repeatedly seeing where AI failed in real work, and realizing I had no coding knowledge to step in and correct it myself. Structure was the only weapon I had. So...
