How to Save a Note to Apple Notes on Your Mac
Apple Notes is useful for long-term organisation. Thoughts is designed for fast capture.
The two workflows can work together.
Capture in Thoughts First
Save an idea quickly in Thoughts.
When you want to move the text into another Mac application, use the available sharing options.
Capture Now, Organise Later
You don't need to decide where every thought belongs immediately.
Thoughts gives you a quick place to save it first.
