Copy-pasting errors into ChatGPT, paying $20/mo for it, knowing it was marking up every single token I sent through their API. Also the coding agent? Arghh, you need some crazy detailed prompt to even get something real! I had a thought I couldn't shake: We have AI that can write code, debug systems, and reason about complex problems — and our workflow is still more fragmented than a 1990s desktop. So I built Syntex AI OS . What it is A full windowed desktop environment. In a browser tab. No install. No setup.
