ChatGPT with the Paper theme by ChatTheme

The Paper look

Not every theme needs a bezel. Paper is for long reading sessions: a warm cream background with a faint dot grid, a serif body font and a single terracotta accent.

It is the theme to pick if bright white feels harsh but full dark mode feels like too much.

  • Cream background with a subtle dot pattern
  • Serif body type
  • Terracotta accent
  • No frame: the layout stays exactly as is

Nothing is hidden, moved or covered. Frames are decoration around the app and never sit over the input, menus or send button.
