​Ready Player Me is a cross-platform avatar creation tool that allows users to design personalized 3D avatars for use across various virtual environments, including games, apps, and social media platforms. Users can create avatars by uploading a selfie, which the platform then converts into a customizable 3D model. Developers can integrate Ready Player Me into their applications using open-source SDKs available for platforms like Unity and Unreal Engine. The platform also offers monetization tools, enabling developers to sell custom avatars and skins to their users.
