Reel

Reel keeps a history of what you copy on your Mac: text, links, code, colors, images and files. Press Shift-Command-V, find the item, hit Return and it pastes into the app you were in.

You can search the history, keep frequent snippets on pinboards, preview images and files before pasting, and read Markdown rendered properly. It is a native Mac app.

Pricing is a one-time purchase, no subscription. Launch price is $11.99 for 1 Mac or $19.99 for 2 Macs (regularly $14.99 / $24.99). There is a 14-day free trial.
