LockIn is a browser extension built for focused studying. Basic Mode blocks a large list of AI websites, while Exam Mode takes it further by blocking AI plus social media, entertainment, blogs, and other distractions. Password protection makes it harder to simply disable when you're tempted. You can also add your own websites to a custom blocklist.
