Slicereader

Slicereader is an innovative reading app for the Mac. Slicereader was designed to help you focus on what you're reading.

It slices up your text into paragraphs, and shows them one at a time using a beautiful, large font on a clean page.

Slicereader comes with a simple bookmarklet. You can drag-drop that to any browsers you use and just click to read the article within Slicereader.

Slicereader understands HTML articles, but also is really adept at reading Markdown.
