I just stumbled across a mention of this as a way to make Obsidian accessible via the web. I did a search on mem.ai on this site, and got lots of hits--but they seem to be false ones. Has anyone looked at this?

Some search strings can confuse simple search engines.

A solution is to do a site-specific search in Google by entering this (including quotes):
"mem.ai" site:www.outlinersoftware.com/topics

This brings up only two posts:

https://www.outlinersoftware.com/topics/viewt/9851/0/search-for-block-based-apps-with-graph-view

https://www.outlinersoftware.com/topics/viewt/9376/0/mem

(I assume that the present post does not yet come up in search results, because it has yet to be indexed by Google, which I expect will happen in the coming hours or days.)

Great tips, and thanks for the links. The second one was packed with info.
