My Chat Faces

Make your AI chats beautiful. My Chat Faces lets you personalize ChatGPT, Claude, Gemini, and Grok with custom backgrounds and chat styling, directly in your browser.

Turn flat, repetitive AI interfaces into something that feels personal. Choose a built-in theme, upload your own wallpaper, and fine-tune the chat appearance with custom bubble colors, text color, opacity, and background brightness.

🎨 3 BUILT-IN THEMES
Choose from Cyber, Fantasy, and Unicorns — three widescreen backgrounds designed to transform your chat space instantly.

📤 UPLOAD YOUR OWN IMAGE
Use any image from your computer. A photo, artwork, wallpaper, illustration, or meme — it is up to you. Your custom image is stored locally in your browser and stays available across sessions.

💬 CUSTOM CHAT APPEARANCE
Go beyond backgrounds. Adjust:
• User bubble color
• Assistant bubble color
• Text color
• Chat surface opacity
• Background brightness

You can preview your style settings in the popup before applying them to the page.

🖱️ APPLY STYLE WHEN YOU’RE READY
Use the built-in Apply Style button to send your color, opacity, and brightness changes to the current tab. This gives you a more predictable and intentional styling flow.

✨ SMOOTH VISUAL TRANSITIONS
Backgrounds fade in with a cinematic 2-second transition. Switching themes uses a smooth fade-out / fade-in animation for a polished feel.

👁️ FULL-PAGE ATMOSPHERE
The visual treatment reaches across the chat interface, including the main conversation area and sidebar elements, so the experience feels cohesive instead of patched together.

📱 MADE FOR EVERYDAY USE
My Chat Faces is lightweight, simple to use, and built for people who spend a lot of time in AI chat tools and want a workspace that feels more inspiring and readable.

🔒 PRIVACY FIRST
No analytics. No tracking. No server calls. No account required. Everything runs locally in your browser.
