Our brain does not need to see the whole sequence of letters to understand what kind of word we see: it reads a couple of characters, the form of the word and finishes the rest in a fraction of a second.
Jiffy Reader allows you to use this trick to increase reading speed. The extension highlights the first letters of words in bold, so the tool smoothly guides your eyes around the page using these fixation points and the brain catches the meaning of the words faster.
In the extension settings, you can enable or turn off the fast reading mode, set the accent interval (for example, to highlight not every word, but after 1-4), and also set the number of characters that will be highlighted in each word: from 1 to 3.
The extension is available for the browser Google Chrome. The source code is available on GitHub. The project is completely free, there are no ads. The developers also plan to release versions for other browsers.
