Draft Persistence
Local drafts on the home flow and server auto-save plus chat history on the writing screen.
Local drafts mainly apply to the home/brief/outline flow before a post is saved to your account. Each browser tab can maintain its own draft in local storage, so you can refresh or close the tab without losing in-progress brief or outline work.
Drafts are automatically cleaned up after 7 days of inactivity. When you return to the app, your most recent local draft may be restored automatically.
Once you're on the writing screen with a generated article, persistence is server auto-save (about 1.2 seconds after you pause typing) plus chat history saved per post. See Auto-Save and Editing your article.
