A reading guide that glides along every line.
GlideMark draws one band that grows as you read. Its edge is always where you are, across spaces, punctuation and line breaks.

Sunlight moved across the desk while the report stayed open. Page nine, page ten, a table of figures, another table. The words were all there and none of them stayed. The next paragraph began the same way the last one had, and you followed it with your eyes and nothing else.

Stop reading

Press GlideMark on the toolbar to try it.
Long lines are easy to lose halfway across
At the end of a line your eyes have to find the start of the next one. GlideMark gives them an edge to follow, so the jump back is easier to make.
What you get
One band that only grows
The highlight or underline runs from the start to where you are and never erases behind itself. It covers every letter, space and punctuation mark as a smooth wipe, with no blinking between steps.
It doesn't touch the page
GlideMark uses the browser's CSS Custom Highlight API, so it changes none of the page's markup. Stopping removes one highlight and one style.
Highlight or underline
Choose a filled band, or a thin line that runs under the text.
Seven colours, or your own
Blue, green, yellow, purple, pink, teal and orange, or any custom colour. The default is the soft apricot.
Start from where you are
Click the page to set where the band begins. The arrow keys nudge it by about a word.
Which pacer should I use?
| Autopace | Cadence | GlideMark | |
|---|---|---|---|
| What you see | One word, centred on a clean screen | A highlight on one to four words | One band or underline that keeps growing |
| What moves | The word itself | The highlight jumps forward a step at a time | The edge of the band, letter by letter |
| What it does to the page | The page is replaced by a reading screen while it runs | Words are wrapped so they can be marked, then restored | Nothing. It uses the browser's own highlight feature |
| Reach for it when | You want no line to lose and nothing else in view | You want to see exactly which words are coming next | You want the lightest guide that never gets in the way |

Questions about GlideMark
Which pacer should I use?
GlideMark is the smoothest and the least intrusive. Cadence is better if you want to see exactly which words are next. Autopace is for when you want one word and nothing else. The table on this page compares them.
Does GlideMark work in my browser?
Skimora is a Chrome extension. GlideMark uses the CSS Custom Highlight API, which is built into every version of Chrome that Skimora supports (147 and later).
Is GlideMark free?
GlideMark is part of the lifetime license. You can try it on this page first.
