A bookmarklet is a tiny link that lives in your bookmarks bar. Click it on any page, in any browser, and MarkWell opens with the link and title already filled in — no share menu, no copy-paste.
Drag to your bookmarks bar
Save to MarkWellIf your bookmarks bar is hidden: Safari — View → Show Bookmarks Bar (⇧⌘B). Chrome / Edge — ⌘⇧B. Firefox — ⌘⇧B.
The button doesn't do anything here — clicking it on this marketing page is a no-op on purpose. It only works once it's sitting in your bookmarks bar and you click it while looking at the page you actually want to save. That click hands the current tab's URL and title to MarkWell and opens the Add Bookmark sheet, prefilled and ready for tags.
Some browsers are picky about dragging a styled button straight off a page. If it doesn't stick, create a new bookmark by hand (any bookmark, any name) and paste this into the URL/location field instead of a normal address:
javascript:(function(){var u=encodeURIComponent(location.href),t=encodeURIComponent(document.title);location.href='markwell://add?url='+u+'&title='+t;})();
markwell://add?url=…&title=…, which macOS routes straight to MarkWell.
