Currently, adding your own assets to the library is not available. The “Create Your Story” feature uses Maybe’s catalogue of assets, which include our beautiful backgrounds, outfits, characters, and hairs. The art in this library is designed to work with the Maybe story engine. In order to keep this high-quality visual for your stories, the library of assets will contain only Maybe-created assets for the time being.
If this feature is added in the future, we will let you know.
