Question 1

How do I change my ChatGPT theme?

Accepted Answer

Install the Oxta Chrome extension, open chatgpt.com, and pick a ChatGPT theme. Effects themes rebuild the chat UI; voice themes appear only during a voice call. CRT Classic is free to use immediately.

Question 2

Is there a free ChatGPT skin?

Accepted Answer

Yes. CRT Classic is a free-forever ChatGPT skin with 7 phosphor palettes, scanlines, and terminal chat. QQ 2005, Windows 98, Tess v1, Nuclear Age, and voice skins are Pro.

Question 3

Do I need an API key to use a ChatGPT theme?

Accepted Answer

No. Oxta is not a separate model. Use your existing ChatGPT account — you do not need to buy an OpenAI API key.

Question 4

What is a ChatGPT theme or ChatGPT skin?

Accepted Answer

A ChatGPT theme (or skin) restyles the chat: bubbles, desktop, scanlines, and voice overlays. Oxta effects themes are full scenes, not a simple color swap.

Question 5

How do I install a ChatGPT theme in Chrome?

Accepted Answer

Install Oxta Chat from the Chrome Web Store, sign in to ChatGPT in the browser, then switch skins such as CRT, QQ 2005, or Windows 98.

Question 6

Will a ChatGPT theme delete or upload my chats?

Accepted Answer

No. Oxta is an isolated overlay on the page. It does not replace your ChatGPT account or upload your conversation content.
