FocusLine – Reading Ruler & Line Reader

About

FocusLine is a reading ruler and line reader that helps you stay focused while reading online. An adjustable guide follows your cursor, making it easier to track text, reduce distractions, and never lose your place on any webpage. Perfect for articles, study materials, emails, and everyday reading.

Once installed, open FocusLine and start reading with a distraction-free reading guide instantly.

A reading ruler is a well-known support for readers with dyslexia, ADHD, or visual tracking difficulties - and it helps anyone who reads a lot online. Students, researchers, editors, proofreaders, and avid readers use a line reader to slow down, focus, and read more accurately. As a dyslexia line reader, FocusLine keeps each line clear without changing the page itself.

🚀 Quick start
1. Click "Add to Chrome."
2. Open any web page, click the FocusLine icon, and switch it on.
3. Move your mouse and the line follows. Tune the color, height, opacity, and mode until it feels right.
