and it also helps with students internal clock

Hi everyone,

Thank you for continuing the conversation and sharing your thoughts about dark mode!

I wanted to clarify that the Dark Reader browser extension we recommend is actually free to use. While the developers suggest a $9.99 donation, it’s completely optional—not required. The extension is also open-source, so schools and organizations can modify it if needed. Additionally, it does not collect any user data. I’ve tested this extension myself and found that it works reasonably well on Khan Academy, especially when using the "Dynamic" theme generation mode.

As for adding an official dark mode directly to Khan Academy, we definitely understand how helpful it would be, especially for those studying at night. It’s something our team has explored. However, implementing a dark mode across a platform as large and complex as Khan Academy would require significant engineering and design resources. We’d need to:

• Build a new design system that supports dark and light themes.
• Update styles across hundreds of pages and components.
• Recreate many static images and graphics to display properly in dark mode.
• Test everything for accessibility compliance to ensure the experience works for all learners.

Because we focus most of our engineering and design resources on developing core learning features and keeping Khan Academy free for everyone, we haven’t been able to prioritize this yet, and it’s unlikely that a native dark mode will be available in the foreseeable future.

That said, we truly value your feedback and have shared it with our team so they can consider it as we plan future improvements. We have an existing tracker for Dark Mode requests and will continue to add new user feedback/posts to it in the future.

Thanks again for your input and for helping make Khan Academy better!
