Claritas blocks the noise so you can do your best work. Smart site blocking, daily time limits, Pomodoro timers, and a study journal — all built into one browser extension.
Six powerful tools in one lightweight extension. No subscriptions, no data collection — just focus.
No account required. No configuration files. Just install and start focusing.
A full breakdown of every feature — so you know exactly what Claritas is doing and why.
Toggle any category on and Claritas immediately blocks all its domains via Chrome's declarativeNetRequest API. Blocked pages redirect to the Claritas blocked screen — complete with a motivational quote and a meme to keep you smiling.
Unlike hard blocking, the Time Limiter lets you visit a site — but only for a set number of minutes per day. When time runs out, you're redirected to the "Time's Up" page and locked out until midnight.
The built-in Pomodoro timer runs work-break cycles and manages your blocking rules automatically. During a break, all blocked sites temporarily unblock. When the break ends, blocking reinstates and Claritas redirects any distraction tabs.
After 3+ hours of tracked focus time, Claritas shows a "Digital Detox Recommended" banner in the popup. A full detox opens a calming full-screen page, suspending all activity for 5–10 minutes so your eyes can rest.
A dedicated journaling page lets you record study sessions with subject, date, duration, score, and notes. Sessions persist locally and you can review your history, track streaks, and see how your scores improve over time.
Schedule any block category to activate automatically on specific days and times. Claritas checks schedules every minute and enforces them without you having to remember to turn anything on.
