Full description
Kairo Reader is a free, open-source RSVP reader and ebook reader designed for focused, distraction-free reading. Read EPUB, MOBI, PRC, AZW, FB2, PDF, DOCX, TXT, Markdown and HTML files using Rapid Serial Visual Presentation (RSVP), a reading method that displays text word by word at a pace you control. Instead of constantly moving your eyes across a page, Kairo keeps words in one focused reading position. Choose your reading speed and work through books, documents, articles and study material with less visual clutter. FEATURES • RSVP reading with adjustable reading speed • Import your own books and documents • EPUB, MOBI, PRC, AZW and FB2 support • PDF and DOCX support • TXT, Markdown and HTML support • Clean, minimal reading interface • Designed for focused, distraction-free reading • Completely free and open source SUPPORTED FORMATS Ebooks: EPUB, MOBI, PRC, AZW, FB2 Documents: PDF, DOCX Text and web: TXT, Markdown, MD, HTML FOCUSED READING WITH RSVP RSVP, or Rapid Serial Visual Presentation, presents text sequentially in a fixed position. Rather than scanning back and forth across a page, Kairo lets you keep your attention in one place while words appear at the speed you choose. Read at a comfortable pace or increase the speed when you want to move through material more quickly. MORE THAN AN EBOOK READER Kairo isn't limited to EPUB books. You can import PDFs, Word documents, Markdown files, text files and HTML content into the same focused reading experience. Use Kairo for novels, articles, coursework, research material, personal notes and other documents. CALM BY DESIGN Kairo keeps the interface intentionally minimal so your reading stays at the centre of attention. No clutter or unnecessary distractions. Just your files, your pace and your focus. FREE AND OPEN SOURCE Kairo Reader is completely free and open source. Digital reading tools should help you focus on what you're reading, not get in the way.
