Questions?

Is it free?

ChatTheme

Yes. Every built-in theme is free. New accounts also get free AI themes to start.

Will it slow the page down?

ChatTheme

No. A theme is a single stylesheet. Nothing runs inside your conversation.

What happens when ChatGPT, Claude or Gemini change their site?

ChatTheme

Your themes keep working. We update ChatTheme when the sites change, not your themes.

Which browsers?

ChatTheme

Chrome, plus Edge, Brave and Arc.

Can I hide parts of ChatGPT I never use?

ChatTheme

Yes. Click Pick in the side panel, point at the buttons or links you don't use and send. Or just ask: "hide the Upgrade button". The message box and send button can never be hidden, and every tweak is one click to undo.

Is the text still readable?

ChatTheme

Always. Every theme, AI ones included, is checked for strong text contrast before you see it.
