Lock In — Focus & Study

Lock In is a productivity-focused Chrome extension designed to help you stay focused, manage your time, and understand where your attention goes online. Start a Lock In session, choose the websites you want to block, and set a focus timer. While your session is active, distracting websites are blocked so you can concentrate on what actually needs to get done. When it’s time for a break, Lock In temporarily restores access without losing your progress or disrupting the pages you already had open. Lock In also helps you understand your productivity over time. Track focus sessions and browsing activity, organize your work into custom categories, and view your activity by day, week, or month to see where your time is going. Key features include: • Customizable focus and break timers • Website blocking during focus sessions • Automatic access restoration during breaks and after sessions • Preserve open pages and website progress when sites are blocked • Custom categories for organizing your work • Daily, weekly, and monthly productivity insights • Session and activity history • Optional Lock In new-tab experience during focus sessions • Clean, distraction-free interface When you aren’t in a Lock In session, Chrome works normally. Lock In stays out of your way until you’re ready to focus. Whether you’re studying, working, coding, writing, or just trying to spend less time distracted online, Lock In gives you the structure to focus when it matters. Block distractions. Track your time.
