Google is offering a web page with Google Assistant commands if you aren't sure what all the topics are that you can ask. While there is a vast pool of queries you can position to the digital assistant software that powers a few of Google's newest products, you might wonder about specific questions you can ask or tasks you can give to Google Assistant that will end up with desired results that it can actually process, and if that's the case this new web page will be able to help with that.
Appropriately titled, "OK Google," the web page is set up in such a way that's ridiculously easy to navigate, complete with material design inspired style, and you can figure out commands for Google Assistant by either searching with the search bar at the very top of the page, or you can simply browse through the categories and things that are already listed. What's more is that the commands are interactive. You can mouse over them and each time you do so the commands will change. For example, the first category is labeled as "People & Relationships," and one of the first commands is a question asking "How old is," followed up by a random person. Most of these seem to be celebrities or other well-known public figures, and when you mouse over another command the person in that first command will change. This happens with all of the commands. It's essentially Google Assistant in a web portal, minus the connectivity with smart home products and third party apps and such, and you can't actually click on anything to get the results because the page only serves as a means to figure out what you can say to Google Assistant that will work.
That being said, Google Assistant can do quite a few things and it's able to answer a lot of different questions thanks to Google's knowledge graph and artificial intelligence technology that's powering it. This can make it challenging to figure out what it is that it can do if you have a product that has Google Assistant installed, and while you could simply just ask Google Assistant and go through trial and error, if you'd rather know before hand, this is a way you can do just that.
