The Copywriter tab may not be in your left navigation bar but the AI Copywriter is still one of the features you can use in your Enji account! In an update in November of 2025, the UI was updated to move to a calendar-based view, and the separate Copywriter tab was removed.
If you had blog, pins, or social media captions under your Copywriter tab that were not scheduled, you did not lose them. There is an "Unscheduled Content" button in the upper right of your Calendar where you can find them. They will be there and you will have that button until all the documents are scheduled to publish.
