I built a quick Action Extension for OS X 10.10+ this morning. It’s called “Preview URL,” and it lets you select text containing a URL, then shows a preview of that web page in a popup.
I built it because SearchLink sometimes gets inscrutable URLs (e.g. the Amazon results), and despite the convenience of that Service, I found myself switching back to my browser too often.
You can find details and download on the project page.
Here’s an action-packed video of the Action in action.
