 - Calf has intelligence now! I'm not sure if the intelligence of a calf, is artificial or not, so I'm not sure about using AI here, or CI. Anyway, you can simply use your favorite AI tool to easily generate a calendar event described as a text in normal human language. For example you can copy/paste a text from your invitation email, or a tweet or where ever you want and Calf will fill the form and create the event for you.
