FocusBar

PDF Support

A premium, modern Chrome extension designed to help you focus on reading by highlighting the current line or paragraph while elegantly dimming the rest of the page.

Read Better.

FocusBar overlays a customizable, draggable, and resizable glassmorphic bar on any webpage or PDF. Dim the background to isolate the text you are reading right now. With new multi-frame support, FocusBar now reaches inside iframes and research viewers, making it the perfect companion for academic papers, long-form articles, and complex documentation.

Focus Mode & Slit Mode
