What they do is ask the visitor from which company they come from. Behind the scenes, this is what I imagine happens: - Kenobi scrapes that website and understands what it does - Has some prompts to transform the text in your website through the lens of your user: eg "Transform this text [your website text here] to appeal to a visitor from this company that does the following [scraped content here]"
Of course internally it might be much more complex than this but this is how I would do this if I had to build it.
