Short answer: Yes, provided you didn't use any Copyrighted images in the creation process, and subject to the Copyright laws in your jurisdiction.
Copyright laws for AI-generated artworks are still evolving, and vary from country to country. It's up to you to check the Copyright laws in your own country.
In jurisdictions where NightCafe is deemed the Copyright holder (as the AI-generation platform), we agree to transfer the Copyright ownership to you - the creator - to use however you like, provided that you didn't use any Copyright restricted images to create it.
That means, as long as you own (or have permission to use) any input images you used, you will be assigned Copyright by us. For style transfer, you must have copyright permission for the content and style images. For text-to-image artworks, you must have copyright permissions for any start and target images. If your creation doesn't use any other images, you're welcome to use it for commercial purposes.
We do our best to ensure that only public domain and royalty-free images appear in the preset styles and free images tabs of the image picker, but we don't guarantee that these images are free of copyright limitations, and it's up to you to double-check.
