Is there a social bookmark manager? networks?

Question

Bookmarks

Recently, more and more often I encounter a problem that I can not quickly find the saved content in the social. networks, and there are more and more of them. The main ones I use are Instagram, YouTube, VK, sometimes I find something interesting on tiktok (seriously). This is not counting the standard browser bookmarks, but here raindrop helps out.
Is there a service that can organize saved posts from different social networks? networks?
