As for LibreTexts, we will try to keep the community abreast of any automated bots that will go in to fix certain accessibility issues automatically (using AI in some instances such as alt-text for images). If you wish to update your own content before that happens, check out any announcements in your newsletter. Be sure you have a verified instructor account in LibreOne.
