I was quite underwhelmed by the demo, I'll try to be as constructive as I can.

The core functionality I expect for such a service is for it to automatically detect who I am, I've seen other marketing services do this, there are ways to map IPs to companies and other techniques. Of course, it's rather creepy and not super helpful to the user, but it may have its (shock) value for making certain kinds of products stand out.

And the personalisation itself... Anyone can make a call to an AI + Search service and generate a new version of the HTML with some slightly modified text, which was not all that different, appealing or accurate in the tests I made. I would suggest upgrading to a higher quality model, proper AI can do much better than this if given the right context.

I suppose it's nice that you are making this easy, if you built your site with a visual website builder this wouldn't be completely trivial to replicate. But still, not a very defensible business for now. I suppose that with good marketing and a serious roadmap to beef this up it could be a viable idea.
