pen.dev
ChatGPT pluginDesign UI on a live canvas
pen.dev is an infinite-canvas design editor for websites, app screens, dashboards, slides and marketing graphics. This plugin opens the editor right in the conversation, so Codex designs on a live canvas while you watch: it lays out screens, builds reusable components and variables, and refines what's already there. Designs are saved as .pen files on your computer: new ones as drafts you also find in the pen.dev desktop app, or next to your code when you ask, ready to commit and to turn into code. Select anything in the editor to point Codex at it, and sign in to pen.dev to let Codex generate AI and stock images and vector artwork.
