“Hey Siri, Add a new Writing task”
This example creates a new task in Things within my ‘Writing’ area, assigned to Today, and presents me with a pre-filled quick-entry window where I can add the title and hit save.
I’ve already created almost 50 Siri Shortcuts, but I haven’t done much in the way of integrating Siri Shortcuts with Things. I’ve only set up a couple Siri Shortcuts to filter my tasks with particular tag/list combinations. Follow the link above, though, for some really good examples of Siri Shortcuts set up to create tasks in Things. The post inspired me to set up a few.
