Available for Firefox Android and Cromite (open-source Chromium-based browser for Android) PERMISSIONS EXPLAINED • Storage: To save your theme preferences locally on your device. • ChatGPT access: To apply your custom themes on "chat.openai.com" and "chatgpt.com" GPThemes believe in transparency. All settings are stored locally on your machine. It does not collect any personal data. You can find the extension's source code here : https://github.com/itsmartashub/GPThemes COMPATIBILITY • GPThemes is designed to provide customization experience for the core ChatGPT interface. It is optimized to work with free accounts and key features. • While the extension will likely function with a Plus subscription and Pro models, some of its styling may not be fully optimized for the advanced UI elements or features unique to that version. • The extension is built to work with all languages, but its visual appearance is currently fine-tuned for English. I'm actively removing English-specific selectors in favor of more multilingual methods with almost every update. • Regular updates to maintain compatibility with ChatGPT changes. I appreciate your patience during any brief disruptions. HOW TO 1. Install the GPThemes. 2. On ChatGPT, there should be floating palette button (top-right) — click it to switch between Light, Dark, AMOLED, or open ⚙️ Settings to customize Colors, Fonts, and Layout. 3. Pin the extension's icon to your browser toolbar (if it's not already). 4. Click the icon to open the popup. 5. Use the toggle in the popup's top-right to show or hide the floating palette button on the ChatGPT page. SUPPORT & KEEP IT ALIVE • If you can afford it and find GPThemes valuable, you can support its development with a pay-what-you-want contribution on KO-FI. Even small contributions help keep it alive, up-to-date and accessible. 🔗 https://ko-fi.com/http417 FEEDBACK • If you encounter persistent issues or have suggestions for improvement, please feel free to open an issue on GitHub or contact me via email.
