Google announced Tuesday the release of its new hardware including the Pixel, its first smartphone, live on YouTube.

The Pixel smartphone is available in two sizes: a 5-inch 1080p display on the Pixel and a 5.5-inch display on the Pixel XL. The phones will feature Google Assistant, a new Siri-like software that will respond to voice commands and act as a personal assistant.

"We believe the next big innovation is going to take place at the intersection of hardware and software with AI at the center," Rick Osterloh, senior vice president of Google's hardware division, said.

Competing with Apple's Siri, Amazon's Alexa, IBM's Watson and Microsoft's Cortana, Google's Assistant expands and meets the growing demand for AI personal assistants, combining search engine functionality with organizational intelligence. Google Assistant can also connect to other smart home devices, like Philip Hue and Nest, as well as other new Google hardware to create a cohesive user experience.

While Google is not completely new to the smartphone space, Pixel is the first phone the company has created on its own. Previous phones like the Nexus were made in collaboration with other brands like Samsung, HTC and LG. Like the old Nexus phones, Pixel uses the latest Android software, but Google has introduced a variety of new advanced features to Pixel including a high-definition camera, smart storage, and quick charge.

DxOMark Mobile gave Pixel's 12.3 megapixel camera a rating of 89, the highest camera rating on a phone to date. The phone will also come with free unlimited photo and video storage.

Additionally, Pixel has the ability to "quick charge," which gives the phone up to seven hours of battery life after just a fifteen minute charge.

In addition to the Pixel smartphone Google is set to release Google Home, Google's rival to the Amazon Echo. The tech giant also introduced Daydream VR, a $79 VR headset slated for release next month. The other new products include a new Wi-Fi router and an updated version of their Chromecast video streaming device.

The Pixel phone starts at $649 for 32 GB of storage, and is available for pre-order today through the Google store.
