I came across this article via The Loop. It’s an article written by Matthew Cassinelli, a member of the Shortcuts (née Workflow) team, about how he powers Reminders with Shortcuts.
When it comes down to it, what Reminders provides for Shortcuts (and you) is really a nice, big bucket for text that you can add to with Siri.
Any time you’re lost in thought, you can just Ask Siri to save that one-liner, and then do something useful with it using Shortcuts instead of letting it drift away in the wind.
He also shares seven Shortcuts he uses with Reminders.
