Here are the most exciting things Google announced at its giant conference (GOOG, GOOGL)

During the keynote of its three-day developers' conference, Google CEO Sundar Pichai focused on Google's plans to bake artificial intelligence and machine learning more thoroughly into all of its services.

In that vein, the company also unveiled a bunch of new products, including two messaging apps and a smart speaker.

Here's what caught our eye:

The coolest thing Google announced was Home, a smart speaker similar to Amazon's Echo.

You'll be able to ask Home general questions through search or get tailored info like local weather or what the traffic is like on your route to work. It can also play music and integrate with other smart-home devices, like Google's Nest thermostats.

The device won't start shipping until later this year, and its price is still unknown.

Google thinks Home will be smarter than Echo, though, thanks to another new product it announced: a conversational chat bot called Google Assistant that leverages all of the company's skills in machine learning, artificial intelligence, and natural-language processing.

Assistant will work across all of a user's devices to have an "ongoing two-way dialogue with Google."

It's like an amped-up version of the company's previous virtual assistant, Google Now, that will pull information seamlessly with other Google services like Search, Maps, and YouTube.

Assistant also powers Allo, a new smart-messaging app that Google says will learn about you as you use it.

The app can tie to your phone number or Google account, and it looks like Facebook Messenger with the ability to share stickers and photos.

What sets Allo apart, though, is its ability to serve up "smart replies" and let you chat with Assistant. For example, if your friend sends you a picture of their pup, Allo could auto-suggest the response "cute dog!" and you could call up local restaurant suggestions just by chatting "@google."
