NostrNet.work notes extension, allows you to draft a note offline, and you can publish it later. It has a lot of rough edges right now, but I will improve it soon.
In a few days, whatever you post using this app will be broadcasted to all the existing relays, giving you the best discoverability possible.

Offline drafts work, just dont close the app.
