There are several ways you can recover missing Rems, whether you've lost one or hundreds.

If you've only just accidentally deleted or changed some Rems, you can undo the change by pressing Ctrl+Z (Command+Z if using a Mac). You can undo multiple changes in a row if necessary, and you can redo changes with Ctrl+Shift+Z if you go too far.

Your Rems may have inadvertently been moved to the wrong location, either because you pressed the wrong button by mistake, or because of a syncing conflict where the Rems were in different places on different devices. Try using Ctrl+P search (Command+P on a Mac) to look for the missing Rems, and move them back to the correct location if necessary.

Deleted Rems are placed in the Trash, which you can access in any of the following ways:

If you find your deleted Rems in the Trash, you'll see an option to restore them to their original location.

Deleted Rems remain in the Trash for at least two weeks before being permanently deleted.

If you're using a Synced Knowledge Base and you created the missing Rems on a different device than the one you're using, it's possible the Rems are still trapped on that device. (Typically this would happen if you didn't have a fully functional internet connection at the time or your device was switched off before RemNote finished syncing.)

If this is the case, you'll be able to find the missing Rems in RemNote on the device where you created them. If they still appear on one device but not the other, make sure both devices are connected to the internet, restart RemNote on both devices, and wait a few moments for syncing to complete.

RemNote automatically makes backups of your knowledge base in many cases, which you can restore from if other attempts to retrieve your Rems have failed. Please see the RemNote Backups article for more details and instructions on finding and restoring a backup.
