It does not change what already-trained models know. If GPT-4 or Claude 3 was trained before your site existed, those weights are fixed. The kit affects future crawls and live AI search products that hit your site in real time.
It does not guarantee placement in any AI response. No tool can do that. The kit gives AI products everything they need to find, understand, and cite you. Whether they cite you in any particular answer is up to them.
It does not legally prevent AI companies from using your content. ai.txt and llms.txt are voluntary, emerging standards. They signal intent. They are not enforceable.
Inside those limits, the kit does what it says: it makes your site readable, identifiable, and citable by the systems that increasingly decide what gets seen.
