There is no need for any external avatar generation software! Retorio is an all-in-one AI coaching platform. It offers a built-in coaching generator feature that generates lifelike avatars based on your input. Retorio's avatars can act according to a pre-configured script or dynamically react to your learners. However, if you prefer to use your own avatars or if you prefer to work with avatar generation software like Synthesia or HeyGen, you can import the content that your generated on these platforms to your Retorio account.
