Features & Capabilities

Ever feel overwhelmed by cluttered webpages, flashing ads, endless sidebars, or massive walls of text?

Zen Reader transforms any supported webpage into a clean, distraction-free reading experience designed to help you stay focused. Whether you're a student, researcher, professional, or someone with ADHD or reading fatigue, Zen Reader helps you read with greater comfort and less mental effort.

Unlike traditional reader modes that simply remove ads, Zen Reader provides a fully customizable reading environment with intelligent focus tools, accessible typography, and thoughtful visual enhancements that help you stay immersed in the content—not the distractions.

Core Features Customizable Focus Anchors Guide your eyes naturally through text with adjustable Focus Anchors. Customize the anchor strength anywhere from 0% to 100% to match your preferred reading style.

Reading Ruler (Deep Focus Mode) Long articles can feel overwhelming when every paragraph competes for your attention. Reading Ruler keeps your current paragraph perfectly clear while gently fading and softly blurring the surrounding content. By reducing visual distractions, it helps you stay immersed in the text, maintain focus, and comfortably read lengthy articles without losing your place.

ADHD-Friendly Reading Experience Designed with cognitive-friendly layouts, customizable focus tools, and accessible typography.
