Feedback about a Visualping alternative using AI to monitor websites

I'm launching an alternative to Visualing called Page Deltas ( https://pagedeltas.com ) to monitor websites using LLMs.

The idea is to ask AI which part of a webpage you want to monitor, and let it summarize detected changes for you.

Useful to monitor your competitors for example (their pricing, products, TOS, etc.).

I'd love to have your feedback on this. Do you think it's useful? Any advice?

Thanks
