The logos open in the chat and stay in your library.\n\nFor new businesses, side projects and quick brand explorations.\n\nLimitations: new concepts as image files; it does not redraw an existing logo, export vector files or check trademarks. 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.",
