opencoworkai/open-codesign ? reverse-engineered prompt

Build me a local first desktop app where I can paste a prompt and quickly turn it into a polished prototype, slide deck, or PDF.

I want it to feel like an open source alternative to Claude Design, with a clean workspace, a prompt box, live preview, and easy export. Let me connect my own API key or sign in with the model I already use, and make setup as close to one click as possible. It should support a few different models, and if needed, look up current docs online so the integrations are actually correct.

The app should save work on my laptop, not force everything into the cloud, and it should be simple enough that I can start from a blank idea and end up with something presentable without a lot of manual design work. Add sensible defaults, a few examples, and make the whole thing feel fast and polished.
