I’m often breaking my reading flow in Safari to look up terms or save references. I want a Safari extension with a companion library app to keep everything in one place. When I select text on a webpage, a small overlay should appear with options to: fetch a definition from a scholarly API, search the term in a research database, or save the selection as a citation. Every saved citation must include the selected text and the page’s URL and automatically sync to the app’s central library so I can review and manage them later.
