Google Keep is a note-taking service included as part of the free, web-based Google Docs Editors suite offered by Google. The service also includes Google Docs, Google Sheets, Google Slides, Google Drawings, Google Forms, and Google Sites.
Google Keep is available as a web application as well as mobile app for Android and iOS.

The app offers a variety of tools for taking notes, including text, lists, images, and audio. Text from images can be extracted using optical character recognition, and voice recordings can be transcribed. The interface allows for a single-column view or a multi-column view.
Notes can be color-coded, and labels can be applied for organization. Later updates have added functionality to pin notes, and to collaborate on notes with other Keep users in real-time.
