Save a page to Urth from any browser
Safari has Urth in its share menu. For Chrome, Firefox, Arc and the rest on the Mac, there's this: a bookmark that, when clicked, sends the page you're on to Urth as a new note — the text you've selected, or the page's text if you haven't selected any — with a link back to the page.
Drag this to your bookmarks bar:
Then, on any page, select some text if you want only that, and click it. Urth comes forward with the note open.
Private, like the rest of Urth
The bookmarklet is a few lines that run in your own browser and hand the page's title, address and text (or your selection) to the Urth app on your Mac. Nothing is sent anywhere else: not to us, not to anyone. You can read all of it by looking at the link.
