How it works

The workflow starts with a form submission containing a website, logo, and optional product image. The uploaded assets are processed first: the logo is prepared for generation, while the product image is analyzed to understand whether it is a UI, product shot, illustration, object, or another type of visual.

Next, the workflow fetches the homepage, extracts navigation links, and uses Claude to select a few useful internal pages likely to contain stronger marketing input. Those pages are fetched and converted into text.

That content is then cleaned and merged into one source. Claude uses it to build structured brand insights and turn them into a full ad concept, including headline, subheadline, CTA, visual direction, and layout direction.

Finally, the concept and uploaded assets are passed to the image model to generate the final ad creative, which can then be exported automatically.

Result

With this workflow, you go from website + assets → brand insights → ad concept → generated creative in one flow, with much less manual prompting and much more structure.
