GPThemes believe in transparency. All settings are stored locally on your machine. It does not collect any personal data.
⚠️COMPATIBILITY & SUPPORT⚠️
• 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 🧵
1️⃣ Install the GPThemes.
2️⃣ 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.
3️⃣ Pin the extension’s icon to your browser toolbar (if it’s not already).
4️⃣ Click the icon to open the popup.
5️⃣ Use the toggle in the popup’s top-right to show or hide the floating palette button on the ChatGPT page.

- (2025-08-21) Ari Rahun: The extension brings styles and settings that were missing. Many site details are covered and with great care. I am currently using a small laptop, and I find that every inch of screen space is valuable. Is there a way to hide elements like the top bar and the info section below the message box? I really like the extension, and it's been super helpful. I appreciate making all features available without a paywall. However, is there a way to support your work? I can see that you put a lot of time into this, and I would like to express my gratitude.
- (2025-08-12) Manuel Peralta Sun: Exactly what I was looking for. Great for quickly changing the look and feel of an otherwise dull UI.
- (2025-08-08) focus: Epic !
- (2025-07-22) Ibrahim Bin Umair: Really loving it! Thanks!
- (2025-06-22) amar: works perfect, simple easy customization, no bs features, sufficient control over fonts. one feature I hope to see is the ability to disable the change theme button, or auto hide it
- (2025-06-20) Jeff D.: Going to give this 5 stars because it does exactly what it says and it does it well. Also the UI is very well done and pleasant to use. I would love this to grow and have a mechanism to "apply" existing/saved themes shared by users. I don't code myself but maybe the theme settings could be exported to some file type and then shared (or have some included with the extension itself) and loaded/switched based on user preference, like Chrome/Vivaldi themes, etc. Also I see there is a way to change the light/dark accent colors, but is there any plan to add background color preference as well? Great work!
- (2025-06-05) Luigi Star31: this is really cool
- (2025-05-30) InvisibleG: Great work! But sadly for 1080p resolution (not sure about other resolutions), the text outputted from ChatGPT is not symmetrical inside the rounded corner chat bubble - the space between the edges and the actual text is not equal to the user input chat bubbles making things look a bit off. Love the ease of use concept, but please allow users to add a background while also allowing them to adjust blur and opacity of the background. The extension deserves this fix & the background features, it will make it complete.
- (2025-04-24) Shailesh Ranjan: This is one of the most well behaved extensions i've ever used. You have done a great work Marta! Thank you so much for this. 1 suggestion, if it is possible, can you by any chance add the option to change the background colour to gradient! that would be super cool. Also while choosing the font, you have to apply the font to see how it looks, so may be if you can show how the font really are on the name of the font, that would be more efficient i think, for example in the section where we can choose font, "quicksand" is written in quicksand font, "worksans" is written in worksans font etc, and yeah, the ui animation is also so good. Keep it up.
- (2025-03-18) Marian Bodnarskyi: I will not underestimate but the light theme looks terrible, it is too gray, please fix it
- (2025-03-09) Timothy Paek: The theme is awesome! I know it's unrelated to its core functionality, but I think a collapsable message feature would make it even better.
- (2025-01-19) Aditya Bhatnagar: this is amazing for real, way better than other extensions i've used a bit of feedback for the dev from my side would be to return to bottom the button parameter should be placed in right most side or left most and its a bit weird looking on the centre bottom + option to import a font from windows, that would be so good, like i want to use apple's sans Francisco but thanks dev! really liked it, in future i hope you could add some animations which look minimal that would be epic
- (2024-12-20) Husain Cyclewala: THERE IS A HUGE CIRCLE COMING AT THE TOP OF THE MESSAGE BOX. PLEASE RESOLVE THIS ISSUEE
- (2024-11-21) haipeng3 sun: everything is good, I think it will perfect if it can change the code's color
- (2024-11-04) Gurvansh Singh Juneja: Amazing I love customization in everything and ChatGPT has been like something that i need everyday so this is just perfect for someone like me. Super Easy to use. Magnificent UI. 100% would recommend!!
- (2024-09-16) Lil Bro: its amazing! but 1 thing... idk how to use it.. its always pink
- (2024-08-29) Sayed Sayed: Sick!
- (2024-07-18) Abhinandan Jain: Nicely Implemented
- (2024-06-02) Rico: Most beautiful theme.
- (2024-04-16) Dunamis: Colour looks great, makes it feel alot better now. Looking forward to seeing what comes next. Great work.
- (2024-03-27) samke: It looks very good, just add an option so the user can change the accent color (e.g. to make it green or red instead of purple).
- (2023-12-22) Sarah: The new colors and updated UI are exactly what I've been searching for. I've tried a few other extensions, but there was always something missing. Personally, this one is hands down the best and most beautiful one for me.
- (2023-12-19) Petar Brađan: I'm absolutely loving the GPThemes Chrome extension! It's given the ChatGPT website a remarkable facelift, making it look more modern and appealing. Before using GPThemes, the ChatGPT website seemed a bit outdated and cluttered. Thanks to GPThemes, it now looks absolutely stunning. The colors have been updated, making the website much more enjoyable. I appreciate the new chat bubbles that clearly separate messages, making everything easier to read. The developer paid close attention to every detail, and it truly shows. The buttons now have cool effects, animations, and different colors, making the website not only functional but also enjoyable to use. When you go to edit a message, GPThemes clearly shows you're in edit mode, because the chat bubble looks different. It's a small detail, but it makes a big difference. The varied button colors enhance visibility and distinguishability, adding to the overall delightful experience. GPThemes seamlessly enhances both dark and light themes, showcasing the developer's attention to detail. These are just a few of the differences that make the website more appealing. A huge thank you to the developer for giving us this much-needed refresh for the ChatGPT website. Your attention to detail is impressive. I highly recommend GPThemes to anyone using ChatGPT. To the developer: keep up the fantastic work! Your dedication to making things better is truly appreciated.
