Focus guard · New Chrome extension

Say your goal. Off‑task pages get stopped.

Type one sentence, like “physics past papers, refraction”, and pick a length. Each page you open is checked against that sentence. On-task pages open. Off-task pages don’t.

  • It judges pages, not whole sites. The YouTube lecture you need opens. The two-hour rabbit hole doesn’t.
  • Off-task pages get a wall, or a gentle nudge if you set it that way.
  • A short focus summary when your session ends.
  • Runs on your computer with Chrome’s built-in AI. No account, and your browsing never leaves your computer.

Planned pricing Not final. Could change before launch.

  • Free$0

    Unlimited sessions up to 1 hour.

  • Pro$3.99/mo or $29/yr

    Locked mode (no early quit), schedules and recurring sessions, a weekly focus report, and your own “always allowed” tools.

Needs a computer that can run Chrome’s built-in AI. Focus guard uses Gemini Nano, which runs on your computer. It needs desktop Chrome on a computer that meets Chrome’s requirements for built-in AI. Not every computer does, and most school Chromebooks can’t run it.
