It's already sorting your email and translating your voice searches, and machine learning will play a bigger role in Google's services moving forward.
Google's parent company, Alphabet, reported its quarterly financial results with revenue and profit both up from a year earlier. New Google CEO Sundar Pichai took part in his first earnings call, and in between discussing the numbers he revealed how important Google thinks machine learning is to its future.
"Machine learning is a core, transformative way by which we're rethinking everything we're doing," he said.
He was putting the spotlight on a branch of artificial intelligence that's getting more attention lately. It involves using computer algorithms that can "learn" over time. A common example is its use in email, where machine learning figures out from watching users' behavior which emails are spam and which should be let through.
At Google, it's long been used for voice search and language translation, and Pichai said the technology has progressed quickly, particularly in the past two years.
"Our investments in machine learning and artificial intelligence are a priority for us," he said. Microsoft, IBM and Facebook are investing in similar areas, and machine learning is showing up in apps for business.
"We're thoughtfully applying it across all our products, be it search, ads, YouTube, or Play," Pichai said. "We're in the early days, but you'll see us in a systematic way think about how we can apply machine learning to all these areas."
He didn't give examples, but it's not hard to imagine where it might turn up. He mentioned machine learning in the context of mobile, for example, where machine learning could determine if a user is at work, at home or in their car, so that their phone can deliver information accordingly.
Thursday was the first time Google's results were reported by Alphabet, the holding company it formed earlier this year, of which Google is just one part. Creating the holding company was a way to separate Google's core businesses -- areas like search, advertising and YouTube -- from longer term bets in areas like self-driving cars.
Next quarter, Alphabet will break out financial results for each division. The goal, it says, is to give more visibility into how the core businesses are performing. For each division, including Google, Alphabet will break out the revenue, net profit and capital expenditures, said CFO Ruth Porat.
On Thursday, though, it was business as usual, and the results last quarter were largely good. Google's overall revenue climbed 13 per cent from a year earlier to $US18.7 billion, while net profit jumped 45 per cent to $US3.9 billion.
Much of the growth came from mobile search, Porat said. Last quarter, the number of searches on mobile devices passed the number on desktops for the first time. India was a particularly strong area for mobile growth.
Revenue from YouTube also grew at a "significant rate," she said, and Google's programmatic advertising business -- real-time, automated purchasing of ads -- was strong.
And Google for Work grew at "a tremendous rate," Porat said. Google Drive for Work passed one million subscribers last quarter for the first time, she said.
Speaking of Google's cloud services for businesses, which compete with Microsoft Azure and Amazon Web Services, Pichai said Google is "investing a lot and playing for the long term"
Not all was rosy, though. Aggregate paid clicks -- the number of times Google made money when a user clicked on an advertisement -- increased 23 per cent from a year earlier, but the amount of money Google received for each click dropped by 11 per cent, continuing a downward trend from the past several quarters.
