About Locus
Locus is a focus extension that helps you maintain deep work by intelligently blocking distracting websites during your sessions. Unlike rigid blockers with fixed allow-lists, Locus uses AI to evaluate your reason for accessing blocked sites.
Key Features
Intelligent AI Gatekeeper
- Try to visit a blocked site and the AI asks why you need it
- Plausible reasons get a temporary pass; weak justifications are denied
- Three difficulty levels (Lenient, Standard, Strict) adjust how strict the AI is
- Customize the AI prompts yourself in Advanced Settings with full control over decision-making
Calendar Integration (No OAuth)
- Connect your calendar feeds without authentication (just paste an iCal URL)
- Supports Google Calendar, iCloud, Outlook, Schoology, and Canvas
- See upcoming assignments and events in the dashboard; click any to start a session with that event as your task
Smart Drift Detection
- Locus monitors if you're staying on-task while temporarily allowed sites are active
- If it detects you're getting distracted (drifting off-topic), it revokes your access and sends you back to the blocker
- Fully configurable: turn drift detection on/off and set the check interval
Local Analytics Dashboard
- Focus minutes tracked daily and weekly
- Streak counter to encourage consistency
- Session history and block attempt statistics
- AI approval/denial breakdowns and drift revocation logs
- Top blocked domains to identify your main distractions
- 14-day bar chart to visualize your focus trends
Customizable Experience
- Light, dark, or system theme support
- Optional notification sound when a site is blocked
- Advanced mode to override the three core AI decision prompts with your own templates
- Template variables: {task}, {domain}, {reason}, {harshness}, and more
- Completely open-source (https://github.com/K-man1/locus-chrome-extension)
Privacy-First
- All analytics are stored locally on your device
- No tracking, no telemetry, no cloud sync across devices
- AI calls are proxied through a rate-limited service that holds no data about your sessions
