Siri has grown a lot over the years, and in doing so, it’s hard to remember everything you can ask it. Hey Siri is a site that hopes to document as many of the commands as possible.
Right now, Hey Siri is packed with 447 commands in 1117 different variations. You can search the site by category or with the search bar to find what you’re looking for. There’s a lot in here, including some stuff I completely forgot about, like weird knowledge questions such as, “How many teeth does a dog have?” or specific weather questions such as, “What’s the visibility outside?” Whether you’re new to iOS or you’ve been using it for years, it’s worth taking a look at Hey Siri just to familiarise yourself with what you can do.
