I've been curious about this. I wanted to build a "Comment on anything" program, but found that it would have to be a browser extension. Iframes can't load most pages, a custom browser is too much friction, and running a proxy is expensive.

So I gave up because I didn't want to write an extension.

Even if you get it working, I'm not clear how you maintain privacy - Loading the whole index from remote is private but expensive. Passing every URL you load to the service is cheap but terrible on privacy.

There are middle grounds like "first 4 letters of a SHA384 of the URL" or bloom filters, but I only skimmed the article and didn't notice which one they're using.
