Show HN: Yumi Reader – Turn any article into distraction-free pure text (github.com)

This browser extension helps by turning articles into text-only reading views using Mozilla's Readability library with custom CSS informed by accessibility and readability research. It follows four design choices based on W3C WCAG 2.2 standards: a sepia background to reduce eye strain, 1.5× line spacing for better readability, 50–75 character line length to reduce eye fatigue, and sans-serif fonts that work well on screens.
