Google Keep lets you create notes and to-do lists that sync across your computer and phone or tablet. It’s handy in a variety of ways: You can record voice memos, and Keep will transcribe them as text notes. You can include images in your notes, and if text is shown in an image, the image shows up in search results. You can create time- or location-triggered reminder notifications based on your notes. You can share your notes with other people and collaborate on them.
