Here's UniversalNotes, an open-source, non-profit browser extension that brings X/Twitter's Community Notes to the entire internet.

Here's my demo showing how it works: https://www.twitter.com/amalsony_/status/1761213504718016763...

and here's the link to the repo: https://www.github.com/amalsony/universalnotes

I'd love to know what you think and what we can improve!
