ikkf!

IKKF: An RSVP reader with extra features such as capturing highlights and taking notes. This tool is meant to be usable both online and offline. CSS/HTML/Javascript are all on the page– if you want, you can save it and use it on your own.

RSVP, or rapid serial visual presentation, is a method of speedreading where the words are displayed on the screen one at a time for a set amount of milliseconds. I like it. I think it’s good for getting through the news, with larger “chunks” (more than one word at a time) preferable for denser prose. I wouldn’t recommend it, of course, if you’re looking forward to luxuriating in Literature, but it is good for just getting the reading done.

I like taking notes as I read, and in most RSVP programs I’ve tried, if I wanted to directly quote the text, then I would have to go search for the string in the source and copy it out. So, I made this tool to add more notetaking/highlighting functionalities on top of the existing RSVP method.

I am a big amateur so the code in this is probably not as clean as it could be. A lot of it is very miscellaneous copypaste, but if any functions are directly lifted from somewhere, I have a comment with the source.
