Does the browser extension pull any actual information or text from a website or just a link back to it?

I am trying to figure out the browser extension. I watched the YouTube video to double check, but all you do is right click and select save page or use the button to tell it to save it. When I look at what is in myReach after saving, I see a bunch of URLS, maybe a sentence from the webpage, and at the top, an option to go to the website.

In my mind, saving a website means grabbing all of the information so it can be viewed offline, not just a link back to the page itself. It seems to be a complicated bookmark with some AI analysis. Webpages do get taken down and I’d rather just be able to have it in myReach.
