Reading Mask Bar

A reading focus bar that follows your mouse to block text below your current line, reducing distractions and improving 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 focus on the line where 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 + bar: shows how far down the document the bar’s top edge is, with a visual progress bar. • 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. • Timer: optional countdown with pause/play controls. • History + word cloud: view the last 20 pages you read and generate a word cloud from titles/headings. • Magnifier: zoom the page while the bar stays fixed to activate. • Word lookup: lock the bar and click any word to see a definition. Use Cases • Staying on the right line in long articles. • Tracking dense technical docs without losing your spot. • Reducing visual clutter by covering everything below your focus line.
