AntiSlack

Block distracting sites and build better browsing habits

AntiSlack helps you break the habit of mindless browsing by adding friction to distracting sites. HOW IT WORKS When you visit a blocked site, you're redirected to a challenge page. Solve a math problem to earn 15 minutes of access. The friction makes you pause and ask: "Do I really need this right now?" KEY FEATURES • Block sites with wildcard patterns (e.g., *.reddit.com, youtube.com/shorts/*) • Math-challenge bypass with Easy, Medium, and Hard difficulty • Nuclear Mode: Time-locked blocking with no bypass option • Per-site custom redirects: Send yourself to a productive alternative • Productivity Score (0-100): Track your browsing discipline • Activity Heat Map: Visualize your patterns across the week • Quick-Block: Right-click any page to block the domain • Cloud Sync: Syncs your settings across all Chrome instances NUCLEAR MODE ☢️ When you need absolute focus, activate Nuclear Mode. Set a duration (30 min to 8 hours), and all blocked sites become completely inaccessible. No math bypass. No exceptions. You can optionally set a passphrase to prevent early deactivation. PRIVACY & SECURITY All data stays on your device or in your Chrome sync storage. Nothing is sent to external servers. • No analytics • No tracking • Built with Manifest V3 for security and performance
