The Screen Reader Description project includes descriptions for videos streaming on various sites. While some sites, like youtube, can be hosted on this website, sites like Crunchyroll can't. While the project maintains descriptions for several shows on Crunchyroll, you will have to download the project's Chrome Extension in order to watch the shows with descriptions.
Once you install the Chrome Extension, you can visit any of the links below. As long as the extension is installed and you are running a screen reader, the description should play immediately.
Not all shows have been fully described. If you are interested in more episodes, or for more shows, please reach out on GitHub.
