Problem Description

I have a service called Mystify Chat (https://c.mystify.nova-network.org/ , password 4bet92) that runs using GPT-3. In terms of functionality, it is great, however, the frontend is not very good. I want to revamp the frontend design to look more like https://codepen.io/qiiutian/pen/QWvewGZ (with automatic width adjustment to around 1300px wide), however retain the same functionality as the base Mystify Chat.

Acceptance Criteria

Able to work completely with OpenAI's GPT-3 API, in chat format. A clean frontend that is the same or very similar to the CodePen linked above, complete with animations for chat etc. Additionally, for other features, there should be an opening animation (chat box opens and gets wider when site is loaded), as well as an interactive sidebar which I will provide.

All these instructions may sound very vague, but I will explain once the bounty is claimed.
