BeeLine Reader is a software system which adds color gradients to digital text to improve reading ability and focus. The text at the end of each line is colored the same as the beginning of the next, so the color of the text acts as a flagpost that directs the reader's eyes through the text more easily. In each line, the color of the text transitions from one color to another, with each character being slightly different than the preceding and following characters.
The system is available as an extension in Google Chrome and Mozilla Firefox, as a PDF viewer, and as an iOS app. These tools are mainly designed for use with web-based text, but can also be used to read Amazon Kindle books on iPad and via browser extension. The tools suppresses colors which already exist in text, such as the blue and red links in . Links are instead underlined. The BeeLine Reader tools have a freemium model, with some functionality available at no cost, but other functionality requiring payment.
The company's website lets readers compare their speed with and without the BeeLine colors. The system has won awards from the United Nations Solutions Summit, Stanford University and The Tech Museum of Innovation, and has been reviewed by educators.
BeeLine Reader's technology is patented and has been adopted by the literacy nonprofit Reading Is Fundamental and the accessibility nonprofit Bookshare. California has bought a state-wide license for its libraries.
The company claims that independent testing has shown that its technology increases reading fluency and reading comprehension. It also claims that BeeLine Reader has been shown to be effective as an assistive technology for special education students, in a study done by Bookshare. A pilot study done by CNET showed that readers using BeeLine Reader on CNET stories read nearly 50 percent further into articles than readers using conventional text.
