Once you launch Memento Database Desktop, you get access to all libraries created from your account and the ones shared with you.

The Welcome page helps you choose where to start: create a new library, manage the ones you’ve already created or select the Subscription Plan to use the full power of Memento Database Desktop:

Note that the libraries created on other devices may not be synced automatically. To start using the remote library you see on the Welcome page, you need to download it.
