Ui/Ux Prototype Design for Ai Tutor Assistant App (Web & Mobile)

I am looking for a skilled ui/ux designer to create a working prototype for an ai tutor assistant application. The application is intended for both kids and adults, featuring customizable avatars for both the user and the AI tutor (e.g., Animals for kids, various personas for adults).

The core functionality will be a voice and text-based conversation interface. This interface should display conversations in a bubble format, with messages clearly numbered to facilitate tracing back steps.

The application needs to be responsive, functioning seamlessly on both web browsers and mobile devices.

In addition to the main conversation screen, the prototype should include designs for the following tabs:
- History (of conversations)
- My Creations (content generated or saved)
- Account Page
- Potentially a Dashboard (basic layout)

The deliverable is a working prototype covering approximately 6 to 8 key screens, showcasing the main user flows and interface elements. The primary goal of this prototype is to be used for seeking funding.

A minimalist design aesthetic is preferred for the interface.

Please note that this project focuses solely on the ui/ux design and prototype creation, not full application development or branding.
