Evernote supports several computer and mobile platforms, including macOS, iOS, Chrome OS, Android, Microsoft Windows, Windows Phone, BlackBerry and webOS, and offers online synchronization and backups.

Evernote was founded by Stepan Pachikov and launched as an open beta on June 24, 2008. By July 2013, the service had gained 65 million users. Evernote is available in both a paid and a limited free version. Using the free version implies a limit on the volume of notes posted each month and the number of devices in use of up to two, which can be increased when you switch to a paid subscription.
