Prism — Reading Focus Line von Sandra

Long articles, dense documentation, wide spreadsheets — your eyes drift. Prism solves it by dimming the entire page except a precise horizontal strip around your cursor, giving you a natural reading guide that moves with you.

No Reader Mode. No layout change. No page reload. It just works — on every website, instantly.

▸ HOW IT WORKS

Move your cursor over any page and Prism draws a focus strip at that exact position. Everything above and below fades back. Scroll, and the strip glides with your pointer as you read down the page.

Three settings, zero complexity:

🔲 Focus line height — Slim (tight single-line focus), Normal (comfortable), Wide (paragraph-width band)

🔆 Dim strength — Light (subtle tint), Medium (clear contrast), Strong (deep focus mode)

Toggle it off in one click whenever you don't need it.
