For putting together ideas or proposals in your work, a note-taking app can be helpful. It’s especially useful if you need to present your ideas to co-workers or collaborate with them on notes. In Microsoft Office, OneNote is the app for this job.
OneNote is pre-installed in Windows 10 and included with Microsoft Office, and anyone can use it for free. In addition to Windows, OneNote is available as a web app, a Mac app, an iOS app and an Android app.
