Evernote allows users to share notes and notebooks with other users through email or public URLs. When sharing a note, the recipient will receive an email with access to the shared content in the "Shared with Me" section of their Evernote account. To create a public URL for a notebook, only individual notes can be shared using this method, as notebooks cannot be made publicly accessible. Users can also integrate Evernote with other apps and services using Zapier or other third-party tools, allowing for automatic sharing and synchronization of content across different platforms.
