Let’s understand the use of AO3.
There is no hard-and-fast rule for using Archive of Our Own. You can start reading right away by visiting AO3’s official website. Use the search bar to find the topic according to your niche.

Many people want to know the process of enabling dark mode on the AO3 website. Reading in blue light for a long time can strain the eyes. AO3 doesn’t provide a simple toggle-style dark mode feature. It comes with a built-in dark screen feature, and it is available only for its signed-in audience. Let’s take a look at the step-by-step instructions on how to enable AO3 dark mode:
Note for people who want to make dark mode permanent: It is simple; follow the same steps and then click on the Use button to fix it. Once it is fixed, Reversi will automatically open in dark mode on any device or browser with the same email address.
(If you want to revert to the light screen, go back to the Reversi page and click on Revert to Default Skin).
Another option that you can try for dark mode in AO3 without signing in is to use a browser extension for dark mode. There are several extensions available out there that can give you the experience of dark mode in AO3. These are some of the free dark mode extensions available that you can try.
You can set them up by simply installing the extension in your browser, then opening AO3, clicking on the extension icon, and enabling dark mode for this domain. Adjust the brightness according to your preference.
AO3 doesn’t have its own application. However, the website is mobile phone-compatible. Users with an account can follow the same steps to turn on Reversi Skin. Meanwhile, users with no account can enable dark mode on their mobile phones. Many updated devices come with this setting and automatically darken the AO3 website.
Or
You can simply install a mobile-friendly browser extension that includes dark themes.
The official way and an alternative way you can easily change the mode of the AO3 website, but I suggest using the official Reversi Skin for authentic and credible work. However, a guest or occasional reader can use the extension.
