Google Home has grown up a lot in the six months since it was introduced. At launch, it could only answer Google queries, but now it has more than 200 third-party skills—"conversation actions" in Google parlance— that you can quiz.
These actions add to Home's Google-created services, which include Netflix, Spotify, and 16 different smart home brands, like Philips, Nest and IFTTT, which you can see here.
The full list of Google Home third-party actions isn't available on the web. For some reason, it's only in the Services tab in your Google Home app. So we copied these third-party actions into a Google Sheet for you, which is updated as of April 20, 2017.
The big difference between Google actions and Alexa skills is that you don't have to activate actions. They're all automatically installed. However, many of the third-party actions—like Uber or August Smart Locks—need to be linked to an account with the relevant service. To do so, go into your Google Home app, tap the Menu button, pick Services, scroll down to the action name, tap on it, and then follow the instructions to add your account.
Most actions can be lit up by saying "OK Google, talk to X." They'll then run you through prompts to get what you want. Some actions can execute more complex commands, as shown in the sample utterances below.
So go ahead, ask your Google Home to order Domino's, mix you a drink, or tell you a Star Wars fact. More actions are sure to come in the future.
