Google Keep's new feature will help you find notes old and new even if you never even bothered slapping a label on them. The free app now organizes your notes based on automatically created topics, such as food, places and travel. Even better, you can look for entries simply by clicking on the search bar to bring up topic shortcuts you can access. Google didn't exactly explain how it works, but Keep likely takes cues from the words you use. If you write down "pack for trip to Paris," the app will automatically associate that entry with travel. Useful, especially if you're too lazy to organize your to-do lists and "notes to self" manually. The new feature is now live on Android and iOS, as well as for Keep on the web.
