The image opens in the chat and stays in your library.\n\nFor posts, presentations, mockups and anything that needs a picture.\n\nLimitations: new images from a description; it does not edit photos you attach in the chat. 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.",
