Focus AI

The Chrome website blocker that judges every page against your task

Task-aware AI blocking

The extension reads each page and judges it against the goal you typed, so work-related YouTube or Docs stays available while feeds and Shorts are refused.

The Quit Wall

There is no one-click off switch. Ending a session early means typing a full surrender sentence by hand, letter by letter, with no pasting allowed.

Three strictness levels

Pick standard filtering, the Quit Wall, or a nuclear mode with no exit at all, and escalate on days when your attention is fighting back.

Urge-surfing rewards

Every time you choose work over the feed the moment is stamped and timed, and banked minutes build into a weekly record of reclaimed time.

Strengths & Pros

+The AI classifies by task context rather than domain, so legitimate work on YouTube or Google Docs is not blocked
+The Quit Wall is genuinely hard to bypass, which is the point for people whose problem is impulsive disabling rather than lack of intent
+About 30 seconds to set up, strict mode by default and no account required
+Solo developer who answers support email personally and turns around fixes quickly, according to publicly visible reviews
