The cost to use Google's new tools is more of your data

At its annual I/O conference, Google announced a slew of new features yesterday that require—or encourage you to share—more of your data. Here are the top four you should know:

1. Google Duplex: Still in the experimental stage, Google Duplex is a human-sounding AI agent that can make phone calls to set up appointments.
2. Pretty Please: Targeted at kids, Google Assistant will have the ability to respond to queries that include the word “please” with phrases like “Thanks for asking so nicely.”
3. Style Match: A new feature of Google Lens, Style Match lets you point the phone at, for instance, a dress and get reviews or info about where you can find similar items.
4. Smart Compose: A Gmail feature that uses machine learning to suggest phrases as you type. For instance, if you type in “Taco Tuesday” as your subject, Gmail might recommend the address of your favorite taqueria. Helpful, but also a reminder that Google knows a heck of a lot about you.
