The most powerful, unapologetic website blocker. Set strict schedules, block doomscrolling, and finally get your work done.
We didn't just build a blocker. We built a system to completely rewire your digital habits.
Set a daily global allowance for social media. Once you hit 2 hours (or whatever you set), you're locked out until midnight.
When Strict Mode is on, you cannot access Chrome's extension page to disable it, and you cannot uninstall it from the Chrome Web Store.
Define your core working hours (e.g., 9 AM - 5 PM). Distracting sites are completely inaccessible during these windows.
Need YouTube for work but hate the algorithm? Hide the home feed, sidebar, comments, and Shorts while leaving search intact.
Mute the noise. Add keywords to your filter, and our engine will dynamically hide tweets containing those words as you scroll.
Track your wins. View a lush 30-day heatmap of your productivity, tracking your app usage and doomscrolling habits day by day.
Three steps to a clearer mind and better output.
Add CoreTime to your Chrome browser. It works quietly in the background, syncing your settings securely across devices.
Add your personalized blocklist, define your working hours, and customize your daily scrolling allowance.
When you try to visit a blocked site, you'll be met with an unapologetic block screen reminding you to get back to work.
Yes. CoreTime is currently 100% free to use. We believe everyone deserves the tools to manage their digital lives without a subscription fee.
If Strict Mode is off, you get a 5-minute "snooze" grace period. If Strict Mode is ON, there is absolutely no bypass. You cannot disable the extension, uninstall it via the store, or snooze the block until your schedule ends.
No. CoreTime is built with privacy first. Site matching and time tracking happen locally on your machine. Analytics are stored in your browser's local storage or synced securely via your personal Chrome profile.
CoreTime securely injects CSS directly into YouTube to hide distracting elements like the Home Feed, sidebar recommendations, and Shorts. This allows you to use YouTube as an educational search engine without falling down a rabbit hole.
