Still reading like it's 2005? Your brain deserves an upgrade. Blitzr is an RSVP speed reader for PDFs, EPUBs, Word docs, and web articles. It flashes one word at a time in a fixed spot — no eye-jumping, no losing your place — so you read faster, with sharper focus. - Your pace: start at 250 WPM, climb past 600 as your brain adapts - Smart pauses at sentence and clause boundaries — speed without sacrificing comprehension - One reader, every format: EPUB, PDF, .docx, web articles, plain text, and free Project Gutenberg titles How RSVP Works Your eyes normally jump between words and back over what you've read — that's what slows you down. RSVP (Rapid Serial Visual Presentation) shows one word at a time in the same spot, so your eyes stop hunting and your focus locks in. Smart pauses at sentence and clause boundaries keep the meaning intact, even as you speed up. Whether you're a student drowning in PDFs or a professional chasing deadlines, Blitzr turns you into an accelerated reader — minus the stress. One Reader, Every Format - EPUB books, with inline illustrations - PDFs, including textbooks and research papers - Word documents (.docx), with inline images - Web articles — just share a link to Blitzr - Plain text and free Project Gutenberg titles - Clean, minimal interface built for long reading sessions Use Cases - Study PDFs — research papers, textbook chapters, lecture notes - Read EPUB books — your library, or free Gutenberg titles - Articles & web text — share a link, speed-read it - Work documents — reports, briefs, Word docs Train Your Brain (Yes, Really) - Improve focus and comprehension - Build consistent reading habits - Finish books faster than ever - Spend less time scrolling, more time learning Features That Matter - Adjustable speed controls (go slow or go supersonic) - Multiple modes: RSVP, Highlight, Classic, and Teleprompter - Distraction-free interface - Fully private — your data stays on your device FAQ Q: Will speed reading hurt my comprehension? A: Not if you build up gradually. Start at a pace you fully understand, then nudge the speed up only when you can still follow along. The built-in pauses do a lot of the work for you. Q: What if I can't keep up? A: Just lower the WPM. Blitzr is yours to pace — slow and steady is how the habit builds. Q: Does Blitzr work offline? A: Yes. Imported files stay on your device, and your reading data is fully private. Getting Started 1. Import a file (EPUB, PDF, Word, or text) or share an article to Blitzr 2. Set your reading speed 3.
