Wrenda

You open your homepage and see products, photos and a long About page. Some of the programs that collect pages for ChatGPT or Perplexity open the same page and find it empty. That happens on many modern websites, which show their text only after code runs in the visitor's browser, a step these crawlers skip. Wrenda sits in front of the site and checks for each request whether a person or a crawler is asking.

People reach the normal site unchanged, while AI crawlers get a rewritten copy in structured text. That copy adds questions with answers and schema data, labels that tell a machine what a product name or a price is. The site says the rewrite only structures facts already on the page. Search engines like Google can get the page after a browser has built it in full.

Setup means changing three DNS records so the domain points to Wrenda, which the site puts at about 15 minutes. Sites that keep their own CDN, for example Cloudflare or Fastly, can add a short snippet that forwards only crawler traffic. New domains start in a shadow mode, which logs what each rule would do while every crawler still gets the original page.

A second part of Wrenda tracks how six AI assistants, among them Gemini and Grok, answer questions about your field. It shows how often your brand comes up next to competitors and which websites the answers draw on. An alert goes out when that share drops.
