LittleJohnny — AI Focus Engine 作成者: LittleJohnny

YouTube without the brainrot. LittleJohnny keeps educational videos and blocks distracting content during focused study sessions.

Stop relying on sheer willpower to beat algorithms designed to distract you.

Every time you sit down to study or do deep work, you are fighting against multi-billion dollar platforms engineered by some of the smartest people on earth to hijack your attention.

You go to YouTube to find a quick tutorial for your assignment. The homepage hits you with a wildly entertaining thumbnail. You tell yourself, "Just one video." Two hours later, your assignment is still blank, and you're watching a 40-minute video essay about deep-sea crabs.

Traditional website blockers don't work because you need YouTube for studying. If you block the whole site, you can't get your work done. If you leave it unblocked, you inevitably get sucked into the algorithm.

That is exactly why we built LittleJohnny.

LittleJohnny isn't just a generic website blocker. It is a ruthless bouncer for your attention. Here is how it actually solves the problem:

1. The YouTube Harvester You don't have to block YouTube entirely. Instead, LittleJohnny lets you choose your level of discipline. Set it to 'Low' to simply weed out the absolute worst brain-rot, or dial it all the way up to 'Strict' and tell the AI exactly what you are trying to study (for example: "React programming"). You can still search for and watch your React tutorials, but the second you try to click a distracting gaming video or vlog, LittleJohnny evaluates the context and instantly redirects you away.
2. No Negotiations Other blockers give you a little prompt that asks, "Are you sure you want to visit this site?" or give you a button to temporarily bypass the block. LittleJohnny doesn't negotiate. If you are in an active Focus Session, there are no bypass buttons. If you try to open a distracting website, you are instantly yanked back to your work tab.
3. Set an Intent and Go Just open the extension, type in what you need to accomplish, set your strictness level and timer, and start. LittleJohnny's engine will sit securely in the background and silently evaluate the links you click to make sure you stay on track.

You don't need more discipline. You just need an unfair advantage against the algorithm. Install LittleJohnny, eliminate the doomscrolling, and finally get your work done.
