The Google Assistant is essentially a chat bot that you can talk too within the new Allo chat app. The assistant is also baked into some new Google hardware, such as the pixel phones. During a quick test of the assistant, I noticed that if you ask it to “tell me an interesting fact” sometimes it will respond with facts from Wikipedia.
As can be seen in the image, when chatting to the bot you can ask for an interesting fact. The bot then responds and a collection of suggested tiles are placed at the bottom of the chat window. One of these tiles suggests looking at the source. Clicking this will prompt you to open https://en.wikipedia.org/wiki/August in a browser or in the Wikipedia app.
Once open a quick scan of the article will reveal:
August is the month with highest birth rate in the United States.
