Set up once, then forget the mouse.

Look at an edge to scroll. Look back at the middle to stop. That's it.

Only when you mean it

Read in peace. No accidental scrolls.

The middle of the page is a dead zone, so reading never moves anything. Scrolling only starts after you've looked into the top or bottom band for a moment, and it speeds up the closer you look to the edge.

Blinks and quick glances are filtered out
Looking at your keyboard, your phone or past the side of the screen does nothing
Pauses while you type, watch fullscreen video, or use another app

Every website

Works where you read.

LazyScroll scrolls whatever is under your gaze: the whole page, or a panel inside a web app.

Smile. It's liked.

The post you're reading gets an outline. Smile at it and LazyScroll taps like for you. It's tuned to your own smile, so a slight one is enough, and being already amused when a post scrolls in doesn't count.

Questions

How accurate is it?

It's webcam eye tracking, so think "which part of the screen", not "which word". After calibration it reliably tells reading the middle apart from looking at the top or bottom band, or at your keyboard. Even light on your face and a camera at eye level help the most. The calibration screen tells you how accurate yours is.

Which browsers does it work in?

Chrome, and Chromium browsers like Edge and Brave. Firefox and Safari aren't supported.

How do I install it before the Web Store listing is live?

Download the zip from the latest release and unzip it. Open chrome://extensions, turn on Developer mode, click Load unpacked and pick the unzipped folder. The setup page opens by itself.

Does it slow my computer down?

Face tracking takes a few milliseconds per frame on the GPU. The camera switches off when the browser window isn't in use, and you can turn LazyScroll off per site.

I moved my laptop and it feels off.

Recalibrate from the toolbar menu (Settings & calibration). It handles normal head movement, but a new desk, chair or camera position needs a fresh 20-second calibration.

Is auto-liking allowed on X?

X's rules discourage automated actions. LazyScroll only likes when you smile, one post at a time, but it's your account; you can turn liking off and keep just the scrolling.
