Tool for focus during study sessions?

I want a distraction-free background for studying online. Any free tools to help?

For focused study sessions, a plain background can reduce visual clutter. A bright white display is soothing and helps keep your attention on the task. I’ve used a free white screen online tool that provides a full-page white display. It’s also useful for screen testing or lighting calls. Just set it to full-screen and minimize other tabs to stay focused.
