Blocks that are hard to undo

Jiyuu runs as a system-level service on Windows 11 — so it keeps working even if you try to close it. Block specific URLs, entire domains, or keywords. Pair it with a password, timer, or usage limit so you can't just turn it off when temptation hits.

Your blocks, your rules

Choose how blocked sites look and how hard they are to deactivate. Whether you want a gentle nudge or an iron-clad lock, Jiyuu has a mode for it.

Jiyuu custom blocking modes — grayscale, mute, cover, and blur options

Choose how a block feels

Grayscale drains the dopamine from distracting pages. Blur makes them unreadable. Cover locks the page entirely. Mute kills audio and video. Pick whatever works for you.

Lock your blocks against yourself

The hardest person to block is yourself. Use password locks, random-text challenges, timers, and usage limits to make sure you can't undo a block on impulse.

Everything else you'd want

Beyond blocking, Jiyuu gives you the tools to actually understand and improve your browsing habits.
