PanelSpec – design UI on real devices, export layout prompts for AI codegen

- PanelSpec is a UI design tool that lets creators arrange interfaces directly on images of real devices (phones, tablets, watches, etc.), rather than on abstract canvases. Once a layout is finished, the tool can export the design as a text prompt that can be fed to AI code-generators (e.g., GPT-4, Claude, Copilot) to produce production-ready frontend code. - The tool is aimed at the growing "AI codegen" workflow: instead of manually writing HTML/CSS or using traditional design-to-code plugins, designers describe the visual layout in natural language, and an LLM writes the code. - It addresses a pain point for solo founders, indie hackers, and fast-prototyping teams who want to iterate UI visually but skip the handoff overhead of tools like Figma or Sketch. - The "real device" background images help designers see how an interface will actually look at specific screen sizes and bezels, reducing guesswork about spacing and proportions.
