OmniFocus can use Siri to create tasks

You can use Siri to create new tasks for OmniFocus for iPhone and iPad. This means you can speak “Add get milk to my OmniFocus list” to Siri and OmniFocus will capture “get milk” as a task in your inbox.

If you want to keep some Siri + Reminders tasks separate from the tasks you want to add to OmniFocus, here’s how to set it up:

• Open Reminders and create a new list to hold the OmniFocus tasks you create with Siri
• Open OmniFocus, go to Settings, then the Reminders Capture option
• Enable Reminders Capture and pick the list you just created in Apple’s Reminders app

The Settings panel will display the basic vocabulary to use with Siri, which ensures your task gets added to the proper list that OmniFocus watches. It’s setup to be “add [whatever your task is] to my [name of list in Reminders] list.”
