X (Twitter) Carousel FAQ
The editor
A design tool built for one shape
Not a general canvas with a carousel preset bolted on. The editor is built around the 4:5 slide sequence — templates, curated font pairings, brand-kit colours and your own images, with the platform safe zones already accounted for.
From a blank slide to a scheduled post without leaving the editor.
