Any websites where you and a friend can both browse on the internet without doing screensharing or LAN?

I'm looking for a website or tool that can be used on the phone, so that my friend who's screensharing over Discord broke can still see what I'm doing on an art website I use without constantly sending screenshots.

basically, looking for a website that allows like a split-screen between two people or literally anything where two people can browse at the same time. Shot in the dark something like that exists, but its worth asking.
