Custom ChatGPT themes, colors, and layout
ChatGPT looks the same for everyone. GPTheme — built into AI Workspace — lets you recolor it, change the font, widen the chat, hide the header and footer, and switch light or dark themes in one click. All from a floating button, right inside ChatGPT.
Color, font, and layout — all in one panel
GPTheme gives you a clean customization panel with everything you need to reshape ChatGPT to match how you like to work.
Color
Pick your accent and background, recolor the entire ChatGPT interface, and make it genuinely yours — from soft pastels to deep dark modes.
Font
Change the typeface and reading experience so long conversations feel comfortable instead of clinical.
Layout
Take control of the reading width, go full width, sync the prompt box, and hide UI you never use — all from one panel.
Stop reading ChatGPT in a narrow column
The default ChatGPT layout wastes half your screen. GPTheme puts the width and the clutter under your control.
Chats & prompt width
Fine-tune the chat reading width and prompt width with simple sliders, so messages aren't squeezed into a narrow column.
Chat full width
Expand conversations to the screen's edge for a wider, more spacious view when you want maximum reading space.
Sync prompt width
Match the prompt field to the chat width for a consistent, balanced layout from top to bottom.
Hide header & footer
Remove the top header and the info below the message box to reclaim screen space and focus purely on the conversation.
A floating theme switcher, always one tap away
Jump between light, dim, dark, and your own custom look from a small floating button — without ever leaving the conversation.
Light & bright
Clean, high-contrast themes for daytime work and well-lit rooms.
Dark & dim
Easy-on-the-eyes dark and dimmed themes for late-night sessions.
Your own accent
Build a signature look — like the pink theme above — and switch back to it any time from the floating theme button.
More than just a new coat of paint
GPTheme is one feature of AI Workspace — the local-first workspace that also brings folders, prompts, highlights, and exports to ChatGPT, Claude, and Grok.
One-click theme switching from a floating button inside ChatGPT

ChatGPT theming, answered
Can I change the theme and colors of ChatGPT?
Yes. GPTheme, included in AI Workspace, lets you fully recolor ChatGPT — accent and background colors, fonts, and layout. You can build a custom look or switch between ready-made light and dark themes from a floating button inside ChatGPT.
Can I make the ChatGPT chat wider?
Yes. The Layout tab includes a chats-width slider and a Chat Full Width toggle that expands conversations to the screen's edge, so messages are no longer locked to a narrow center column. You can also sync the prompt box width to match.
Can I hide the ChatGPT header or footer?
Yes. GPTheme can hide the top header and the info bar below the message box, giving you a cleaner, more focused, distraction-free workspace with more room for the conversation itself.
Does changing the ChatGPT theme affect my data or account?
No. GPTheme only restyles the page in your browser. It does not touch your conversations or your OpenAI account, it requires no login, and your theme settings stay local on your device.
Is GPTheme free?
GPTheme is part of AI Workspace, which is free to start. You can install it from the Chrome Web Store and begin customizing ChatGPT immediately, with no credit card required.
