Your eyes stay still
Each word appears in the same place. You can focus on the words as they arrive, pause to see the sentence, and move back whenever you need.
The red letter
One letter near the middle of each word is red, and every word is positioned so its red letter lands on the same spot as the last one. The red letter gives you a fixed point to focus on.
It keeps the rhythm
The slider sets your cruising speed. Sentence ends get a longer pause, commas a shorter one, and long words stay up a little longer, so it reads like prose, not like a metronome. A second slider widens your view: short words appear together, so you take in more at each glance at the same speed.
What you can feed it
| Format | Notes |
|---|---|
| Plain text, Markdown | The simplest and the best. |
| Ordinary text PDFs. Scanned pages contain no text and will not work. | |
| Word (.docx) | Text and headings. Tables are read row by row. |
| E-book (.epub) | Chapter by chapter. Not DRM-protected books. |

| Pasted text | Copy anything, paste it in. |
In the free reader, files and pasted text stay in your browser. For a link, our server fetches the document and passes it to your browser without keeping it. Unfair Advantage is where AI comes in, and only for a book you choose to bring.
