A digital twin of a website is a live model of the site built from a single crawl, held as one graph and inspectable from the point of view of each thing that reads it.
Instead of running a separate tool for each question, you crawl once and keep the result. The pages become nodes. The links become edges. The passages become vectors. Every lens then reads the same twin. The audit, the link graph, the answerability heatmap and the see as bot view all describe one shared model rather than re fetching the page each time.
The value is that the views stay in sync and the history accrues. You can see how a browser, a crawler and an AI agent each read the same page, side by side, and you can watch the numbers move as you change the site.
This is where Kenovar is going. The one shot tools prove the idea on a single URL. The twin holds your whole site and lets an analyst, or another agent, reason over it.
