Question: Is there a service that allows students to practice writing skills and build their own projects with customizable avatars?

Voki is an education site that uses customizable talking avatars to get students more interested in subjects like English Language Arts. Teachers can create lessons and assignments, and students can use the avatars to try out writing and answer questions. Voki has features like easy avatar customization, classroom management tools and a prepackaged curriculum, so it's a good option for writing and learning.

Poly.AI lets you create and interact with more advanced AI characters tailored for your needs. You can use it for creative projects like writing stories and novels, with advanced creation tools and custom AI characters that speak in your own voice. That can make dry subjects more interesting and fun, and let you express yourself and socialize.

If you want to use AI to generate animations, Krikey lets you create talking avatar videos even if you don't know the first thing about animation. You can customize 3D talking avatars with voiceovers, text and backgrounds, and use a variety of templates for different purposes. It's good for students, teachers and marketing people, so it's a good option for creative projects.

Also worth a look is Sudowrite, an AI writing assistant designed to help fiction authors get past writer's block. It can generate ideas, create outlines, write drafts, edit and refine them with large language models like GPT-3 and GPT-4. That can be useful for students working on fiction projects, giving them practical tools to help them be more creative and productive.
