Overview
Product summary
Review the store description, core capabilities, and common use cases.
A common technique recommended for people who struggle to read and retain the information as they read is to use a ruler to read every line.
This add-on creates a line across the webpage that follows the cursor and darkens the lower half to recreate this technique.

THE exact reading ruler I need 👍🏻
Works phenomenally. Does a really good job of keeping me focused on my readings.
