NickChalevas/Internal-linking-tool ? reverse-engineered prompt

Build me a simple internal linking tool for marketing.

I want a page where I can paste one or more target URLs and a list of keywords, then the tool should find or suggest relevant URLs on the site that can be used for internal links. It should feel like a small web app that’s easy to use, with a clean form on the front end and a results page that shows matched URLs, the keyword they relate to, and a short note about why they fit.

Please make it practical for marketing work, so it should help me discover linking opportunities quickly, not just dump raw data. If it helps, include a way to process the input and return the results in a readable format. Keep the UI simple and professional, and make sure it works smoothly in a browser.

If you need to check current docs or examples online to fill in any gaps, go ahead and do that.
