Ask HN: product idea, tool to create ui guider for website

Hi, I am thinking about creating tool for websites to make fast and easy user interface guiders (arrows and text which could over time dynamically describe how interface works). Example of such guider is here https://www.videopixie.com/console/8rLaaBBwQACZeP83IjzkAg Thanks to such guiders visitors who come first time to given website can really fast understand what is going on and how to use this website. What do you think? Is my idea for product right or no?
