Overview

Tell ChatGPT chats apart with custom colors and large titles. Spot mix-ups between tabs and windows when using multiple chats.

A color of your choice for each chat. 🎨 ■ Getting started ① After installation, reload any open ChatGPT pages. ② Click the extension icon. A colored banner and title will then appear for that chat. Use the banner’s color and display menu to adjust colors and sizes. ■ Main features • Choose a banner and frame color for each chat. • Display the chat name prominently at the top of the page. • Adjust banner height, frame thickness, font size and text color. • Click the chat name in the banner to edit the actual name in ChatGPT. • Hide the banner with ×, or use the popup to turn the extension on or off globally or for each chat. • Save per-chat settings and share them across tabs in the same browser profile. • Interface available in seven languages. Note: Chat name editing is available only when ChatGPT’s display language is Japanese or English. The chat must be visible in the sidebar; if its folder is collapsed, it cannot be renamed. ■ Supported environment Supports the official ChatGPT website (chatgpt.com). Desktop apps, mobile apps and other AI services are not supported. New chats can be used once a conversation has started and a chat ID has been assigned. Changes to ChatGPT’s interface may make some features unavailable. ■ Privacy The extension does not collect or save conversation messages or the contents of the message input field, and sends no data to an external server of its own. Settings are stored in your browser, and chat IDs are used to identify chats. It reads and interacts with page elements to adjust the display and rename chats. The source code is publicly available on GitHub, so anyone can review how the extension works. Developed by marusin tools If you enjoy using the extension, a rating or review would be appreciated.
