Reading Mask Bar

A focus bar with a transparent reading strip and Read Aloud (TTS) to reduce distractions and improve reading flow.

Reading Mask Bar keeps your place by dimming everything below your current line. Instead of highlighting text, it hides what’s underneath so your eyes stay anchored on the last visible line. Move the bar with the mouse, scroll the page with the wheel, and see exactly what percent down the document the bar’s top edge sits. Features • Focus mask: a horizontal bar that darkens/hides content below your current line; move it up/down as you read • Percent indicator: shows how far down the document the bar’s top edge is • Adjustable height: set the bar height as a percentage of the viewport • Lock/unlock: lock the bar in place while you scroll, or unlock to reposition freely • Custom appearance: choose color and opacity; settings persist automatically Use Cases • Staying on the right line in long articles • Helping students keep place in lessons • Tracking dense technical docs without losing your spot • Reducing visual clutter by covering everything below your focus line Privacy No data is collected, stored, or sent anywhere.
