Banner thinks in proportions. Same person, three platforms, three aspect ratios, three banners — built for the format they live in, not stretched to fit it.
Banner is a Claude plugin for generating profile headers — for LinkedIn, X, YouTube, Facebook, or any surface that asks for a banner-shaped image and deserves better than another stock gradient. Tell Claude who you are and what you want the banner to say. Banner sets the type, picks the composition, and renders the artwork in your conversation.
The premise: every social platform hands you a wide rectangle and asks what do you want this to say about you? Most people answer with a sunset, a stock photo, or a faded blue gradient. The header is doing the work of a billboard while wearing the clothes of a screensaver. Banner aims for the billboard.

Iteration is the point. Describe the direction; Claude renders an option; you push back. Bigger type. Less gradient. Lose the centerpiece. Try it on cream paper. The plugin is a sketchpad sized to a banner, not a template generator with locked layouts.
Banner ships as a single .skill bundle.
Download it, drop it into your Claude environment, ask
for a header.
“Make me a LinkedIn banner.”
Banner asks who you are and what you do, then proposes a direction. Skip the questions if you've already told Claude who you are — your memory is enough.
“Bigger type. Hot orange. Lose the photo.”
Push back in plain language. Banner re-renders. Iterate until it looks like you, not like a template.
“Now make me an X header in the same family.”
Banner respects the visual family across platforms. You're not making three banners — you're making one identity in three formats.
