Will it slow the page down?
No. A theme is a single stylesheet. Nothing runs inside your conversation.
What happens when ChatGPT, Claude or Gemini change their site?
Your themes keep working. We update ChatTheme when the sites change, not your themes.
Which browsers?
Chrome, plus Edge, Brave and Arc.
Can I hide parts of ChatGPT I never use?
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?
Always. Every theme, AI ones included, is checked for strong text contrast before you see it.
