The cover opens in the chat and stays in your library.\n\nFor self-published authors, newsletters and book clubs.\n\nLimitations: front covers as image files; it does not lay out the spine and back cover or publish the book. Making a file needs a signed-in MegaScenes account and runs in it; nothing is made until you confirm. Not for sexual or adult content or for real people's likeness. Files are made by generative models and saved in your MegaScenes library.",
