Primal's Nostr Tools include the following:

Premium Relay:
The Primal Premium relay is a high- performance Nostr relay that only accepts content from Primal Premium users. Posting to this relay improves your visibility on the Nostr network because it guarantees high signal and lack of spam to any Nostr user that reads from it.

Media Management:
An interface to manage and delete all of your uploaded content. 

Contact List Backup:
I assume this is self explanatory, but the tool doesn't show a lot of information on this yet.

Content Backup:
You can rebroadcast and download your Nostr content, including: 
Reactions, Notes, Encrypted Direct Messages, Reads, and All Events.
