"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 in your workspace, next to your code, 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."
