Make Ad Images with Nano Banana Pro in Claude

How to generate ad images with Nano Banana Pro directly in Claude using Polaris MCP: connect once, describe the shot, pick options, get your image.

GuideJul 15, 2026·3 min read

To make ad images with Nano Banana Pro, connect Polaris to Claude as an MCP connector, then ask Claude in plain chat for the image while attaching your product photo. Claude surfaces the picks as tappable option cards, and Nano Banana Pro renders the image right inside the conversation.

What Nano Banana Pro covers

Nano Banana Pro is one of the image models available through Polaris for ad stills: product shots, lifestyle-style compositions, and static concepts you can run as standalone ads or use as a reference frame for a video ad later. It sits alongside GPT Image 2 as an image option inside the same chat-based workflow, so switching models is just a different answer on the option cards, not a different tool.

Step-by-step: generating in Claude

  1. Add the connector. In Claude, add the Polaris MCP connector at polarisugc.com/api/mcp and authorize it once. After that, Polaris is available in any chat, no separate login per session.
  2. Attach your product. Drop in a product photo, or paste a short brief describing the product and the shot you want, directly in the chat message.
  3. Ask for the image in plain language. Tell Claude what you want, for example an ad still with a specific mood, background, or angle. No prompt syntax required.
  4. Pick settings from the cards. Model (Nano Banana Pro), aspect ratio, and other options show up as tappable cards in the chat. Confirm your picks and Claude passes them straight to Polaris.
  5. Watch the live panel. A Polaris panel opens in the conversation and renders progress, typically finishing in roughly 20 to 180 seconds, then shows the finished image inline.
  6. Recreate or iterate. If the composition is close but not quite right, use one-click Recreate to get a variation without re-typing the whole brief.

The web app exists as a secondary surface if you'd rather work from a dashboard, but the chat-first flow inside Claude is the primary way Polaris is meant to be used.

Pro tips

  • Be specific about what should stay fixed (the product itself, label text, packaging) versus what Claude has freedom to vary (background, lighting, framing).
  • Generate a few variants in parallel rather than iterating on one image serially. It's faster to pick a winner from a small batch than to nudge a single image toward perfect.
  • Use Nano Banana Pro stills as the anchor frame when you later want a matching video ad, so the video and static creative share a consistent look.
  • Run finished copy or on-image text through Copy Judge before you ship, especially for claims-heavy categories.

Honest caveats

Polaris builds ad images around your actual product from your photo or brief; it does not pull from a stock-avatar or stock-model library. Even a strong-looking still is not guaranteed to convert; treat every image as a hook to test against your existing creative, not a finished answer. If you operate in a regulated niche, keep any claims in the ad copy or on-image text compliant — avoid disease, cure, or guaranteed-result language regardless of how the image looks.

Frequently asked questions

Do I need the Polaris web app to use Nano Banana Pro?
No. The primary workflow is inside Claude: add the MCP connector once, then ask for images in chat. The web app is a secondary surface for anyone who prefers a dashboard.
How long does a Nano Banana Pro image take to generate?
Generation typically finishes in roughly 20 to 180 seconds, with a live panel in the Claude conversation showing progress as it renders.
Can Nano Banana Pro use a real person's likeness?
Polaris builds ads around your product from your own photo or brief; it does not clone named real people or pull from a stock-avatar library.
What if the generated image doesn't match what I wanted?
Use one-click Recreate to get a variation, or adjust your brief and regenerate. It's normal to iterate a couple of times before landing on the right composition.
