RSVP SHIFT
Chrome extension for speed reading
Privacy-focused Chrome speed-reading extension using Rapid Serial Visual Presentation (RSVP) with optimal focus-letter alignment.
subjectEXECUTIVE SUMMARY
When reading lengthy online articles, documentation, or technical papers, the human eye wastes up to 80% of its time on physical saccadic movements (moving between words and tracking line breaks) rather than processing information.
RSVP Shift eliminates eye strain and saccadic overhead by presenting words one by one at a fixed screen coordinate, highlighting the Optimal Recognition Point (ORP) — the exact letter where the brain naturally recognizes word meaning.
Built strictly on Chrome Manifest V3, RSVP Shift requires zero external network permissions and processes 100% of highlighted text locally on your device. It features punctuation-adaptive pacing, keyboard-first navigation, and a scrubbable timeline.
Traditional reading requires continuous eye movement across lines of text, causing visual fatigue and limiting comprehension speed when consuming dense technical documentation or news.
RSVP Shift isolates words at a fixed focus point with custom punctuation delays and a distraction-free full-screen overlay.
