Google knows many, many things about you, perhaps even that you can be a bit forgetful sometimes. To help you remember your plans, the company has started testing a feature that takes possible events from Gmail or other Google services and turns them into Google Now cards. For instance, if it infers that you're planning a day out based on an email thread, the new feature will automatically turn it into a card and will ask if you'd like to add the event to your calendar. It's really not that much different from Now pulling flight or hotel reservation info from your Gmail account. According to Android Police (who first reported its existence), you can choose whether to continue getting event suggestions on Google Now's settings page. So, when you do get the feature, you can switch it off if it starts feeling creepy and turn it back on if that calendar's looking suspiciously empty.
